We find that a double Arrhenius temperature dependence with activation energies &lt;em&gt;E&lt;/em&gt;&lt;sub&gt;1&lt;/sub&gt; ∼ 0.1 kJ/mol and &lt;em&gt;E&lt;/em&gt;&lt;sub&gt;2&lt;/sub&gt; ∼ 10 kJ/mol fits the folded and ligand-free state response. The higher activation energy is consistent with the so-called protein dynamical transition associated with beta relaxations at the solvent–protein interface. The lower activation energy is consistent with correlated structural motions. When the structure is removed by denaturing, the lower-activation-energy process is no longer present. Additionally, the lower-activation-energy process is diminished with ligand binding but not for changes in the internal oxidation state. We suggest that the lower-energy activation process is associated with collective structural motions that are no longer accessible with denaturing or binding.&lt;/p&gt;

Combining single-crystal anisotropy measurements with density functional calculations, we assign the phonon frequencies and interrogate how specific phonons behave with melting. While nearly all the low-frequency phonons continuously red-shift with heating and melting, the lowest-energy phonon polarized along the c-axis blue-shifts at the melting temperature, suggesting an initial structural change immediately before melting. We find that the kinetics follow a 3D growth model with large activation energies, consistent with previous differential scanning calorimetry (DSC) measurements. The large activation energies indicate that multiple H-bonds must break collectively for the transition. The results suggest the generality of the kinetics for molecular crystals and that THz TDS with picosecond resolution could be used to measure ultrafast kinetics.&lt;/p&gt;

It is the only known photoactive protein that uses a carotenoid, canthaxanthin, as its chromophore. The structure of OCP consists of two globular domains, connected by an unstructured loop, that forms a hydrophobic pocket for the carotenoid. In low light, canthaxanthin bound OCP is inactive and appears orange. Illumination by strong light results in an active state that interacts with the PBS to induce fluorescence quenching, a red appearance and conformational changes that include a 12Å shift by canthaxanthin into the N-terminal domain. Terahertz (THz) dynamical transition measurements and anisotropic terahertz microscopy are used to measure the intramolecular structural dynamics in the inactive and active states, which can be induced by photoexcitation or chaotropic salts. The measurements indicate that the active state has a decrease in structural flexibility, which may be related to enhanced interactions with the PBS.&lt;/p&gt;</style></abstract><issue><style face="normal" font="default" size="100%">3</style></issue><work-type><style face="normal" font="default" size="100%">Meeting Abstract</style></work-type><accession-num><style face="normal" font="default" size="100%">WOS:000513023201290</style></accession-num><notes><style face="normal" font="default" size="100%">ISI Document Delivery No.: KK8YX&lt;br/&gt;Times Cited: 0&lt;br/&gt;Cited Reference Count: 0&lt;br/&gt;McKinney, Jeffrey A.

We measure the polarization rotation (Re[theta(F)]) and ellipticity (Im[theta(F)]) of transmitted radiation through thin films as the sample is rotated. We observe a twofold rotational symmetry in theta(F), which is associated with linear dichroism (LD) and occurs when electromagnetic radiation polarized along one direction is absorbed more strongly than radiation polarized in the perpendicular direction. Such polarization anisotropies can be generally associated with symmetry breakings. We measure the amplitude of the LD signal and study its temperature, energy, and doping dependence. The LD signal shows a resonant behavior with a peak in the few hundred meV range, which is coincident with the midinfrared optical feature that has been associated with the formation of the pseudogap state. The strongest LD signal is found in underdoped films, although it is also observed in optimally and overdoped samples. The LD signal is consistent with an electronic nematic order which is decoupled from the crystallographic axes as well as novel magnetoelectric effects.&lt;/p&gt;</style></abstract><work-type><style face="normal" font="default" size="100%">Article</style></work-type><accession-num><style face="normal" font="default" size="100%">WOS:000562627700004</style></accession-num><notes><style face="normal" font="default" size="100%">ISI Document Delivery No.: NE5GO&lt;br/&gt;Times Cited: 0&lt;br/&gt;Cited Reference Count: 30&lt;br/&gt;Cited References: &lt;br/&gt;     Acbas G, 2009, PHYS REV LETT, V103, DOI 10.1103/PhysRevLett.103.137201&lt;br/&gt;     Armitage NP, 2014, PHYS REV B, V90, DOI 10.1103/PhysRevB.90.035135&lt;br/&gt;     Arpaia R, 2018, PHY REV MATER, V2, DOI 10.1103/PhysRevMaterials.2.024804&lt;br/&gt;     Basov DN, 2005, REV MOD PHYS, V77, P721, DOI 10.1103/RevModPhys.77.721&lt;br/&gt;     Blumberg G, 1996, PHYS REV B, V53, P11930, DOI 10.1103/PhysRevB.53.R11930&lt;br/&gt;     Cerne J, 2000, PHYS REV LETT, V84, P3418, DOI 10.1103/PhysRevLett.84.3418&lt;br/&gt;     Fauque B, 2006, PHYS REV LETT, V96, DOI 10.1103/PhysRevLett.96.197001&lt;br/&gt;     Fridman I, 2011, PHYS REV B, V84, DOI 10.1103/PhysRevB.84.104522&lt;br/&gt;     George DK, 2012, J OPT SOC AM B, V29, P1406, DOI 10.1364/JOSAB.29.001406&lt;br/&gt;     Halperin B.

The OCP switches from resting state to photo protective state with intense blue light illumination. Questions persist as to why OCPR interaction increases with the PBS over that with the OCPO. Here we examine the role of long-range intramolecular vibrations within OCP. Using Stationary Sample Anisotropic Terahertz Microscopy (SSATM) we measure changes in the intramolecular vibrations with photo switching. We report the first observation of switching in the intramolecular vibrations with photoexcitation. Results suggest that there is a stiffening of the molecule in the photo protective state. This increase in structural stability may enhance the interaction with the PBS change in OCP interaction with PBS. In low light, carotenoid bound OCP appears orange (OCP &lt;sup&gt;o&lt;/sup&gt; ) and is inactive. Illumination by strong light converts OCP to the active, red (OCPR) state, which interacts with the PBS. A comparison of anisotropic THz microscopy measurements of dark adapted (OCP &lt;sup&gt;o&lt;/sup&gt; ) and illuminated OCP crystals indicate differences in their vibrational modes that may be important for OCP-PBS interactions.&lt;/p&gt;

It is important to ensure the near field geometry used does not introduce spectral artifacts. For example, many scanning techniques can be strongly influenced by the interaction between the scattering tip and the sample. Here we examine the spectroscopic effects of a 200 μm diameter aperture for THz near-field measurements. We use HFSS to model free-space transmission through samples with resonant absorbance as a function of sample thickness, lateral sample width, and aperture diameter. We examine the transmitted power and spectral fidelity for coupling of transmitted THz light onto a detector. These studies inform corrective post-measurement analysis algorithms and design of near-field detection systems.&lt;/div&gt;

For most of the 20th Century, terahertz radiation, then referred to as sub-millimeter wave or far-infrared radiation, was mainly utilized by astronomers and some spectroscopists. Following the development of laser based terahertz time-domain spectroscopy in the 1980s and 1990s the field of THz science and technology expanded rapidly, to the extent that it now touches many areas from fundamental science to &#039;real world&#039; applications. For example THz radiation is being used to optimize materials for new solar cells, and may also be a key technology for the next generation of airport security scanners. While the field was emerging it was possible to keep track of all new developments, however now the field has grown so much that it is increasingly difficult to follow the diverse range of new discoveries and applications that are appearing. At this point in time, when the field of THz science and technology is moving from an emerging to a more established and interdisciplinary field, it is apt to present a roadmap to help identify the breadth and future directions of the field. The aim of this roadmap is to present a snapshot of the present state of THz science and technology in 2017, and provide an opinion on the challenges and opportunities that the future holds. To be able to achieve this aim, we have invited a group of international experts to write 18 sections that cover most of the key areas of THz science and technology. We hope that The 2017 Roadmap on THz science and technology will prove to be a useful resource by providing a wide ranging introduction to the capabilities of THz radiation for those outside or just entering the field as well as providing perspective and breadth for those who are well established. We also feel that this review should serve as a useful guide for government and funding agencies.&lt;/p&gt;</style></abstract><work-type><style face="normal" font="default" size="100%">Review</style></work-type><accession-num><style face="normal" font="default" size="100%">WOS:000392153700001</style></accession-num><notes><style face="normal" font="default" size="100%">ISI Document Delivery No.: EI0HL&lt;br/&gt;Times Cited: 541&lt;br/&gt;Cited Reference Count: 209&lt;br/&gt;Cited References: &lt;br/&gt;     Adam AJL, 2011, J INFRARED MILLIM TE, V32, P976, DOI 10.1007/s10762-011-9809-2&lt;br/&gt;     Ahmed SS, 2012, IEEE MICROW MAG, V13, P26, DOI 10.1109/MMM.2012.2205772&lt;br/&gt;     Alliance N., 2015, CISC VIS NETW IND GL, P1&lt;br/&gt;     [Anonymous], 2013, 178512012 IEEE&lt;br/&gt;     [Anonymous], 2014, IEEE T ELECT DEVICES, V61&lt;br/&gt;     [Anonymous], 2012, 178522016 IEEE&lt;br/&gt;     [Anonymous], 2015, P17852 IEEE&lt;br/&gt;     Appleby R, 2015, P SOC PHOTO-OPT INS, V9462&lt;br/&gt;     Arnone DD, 1999, PROC SPIE, V3828, P209, DOI 10.1117/12.361037&lt;br/&gt;     Ashworth PC, 2009, OPT EXPRESS, V17, P12444, DOI 10.1364/OE.17.012444&lt;br/&gt;     AUSTON DH, 1988, IEEE J QUANTUM ELECT, V24, P184, DOI 10.1109/3.114&lt;br/&gt;     Barbieri S, 2011, NAT PHOTONICS, V5, P306, DOI [10.1038/NPHOTON.2011.49, 10.1038/nphoton.2011.49]&lt;br/&gt;     Barker RJ., 2005, MODERN MICROWAVE MIL&lt;br/&gt;     Basov DN, 2011, REV MOD PHYS, V83, P471, DOI 10.1103/RevModPhys.83.471&lt;br/&gt;     Bauwens M.

Structural collective mode frequencies have been calculated to lie in this frequency range, and the density of states can be considered a measure of flexibility. A dramatic increase in the THz response occurs with oxidation, with the largest increase for lowest hydrations and highest frequencies. For both oxidation states the measured THz response rapidly increases with hydration saturating above ~25% (g H&lt;sub&gt;2&lt;/sub&gt;O/g protein), in contrast to the rapid turn-on in dynamics observed at this hydration level for other proteins. Quasi-harmonic collective vibrational modes and dipole-dipole correlation functions are calculated from the molecular dynamics trajectories. The collective mode density of states alone reproduces the measured hydration dependence providing strong evidence of the existence of these collective motions. The large oxidation dependence is reproduced only by the dipole-dipole correlation function, indicating the contrast arises from diffusive motions consistent with structural changes occurring in the vicinity of a buried internal water molecule.&lt;/p&gt;</style></abstract><issue><style face="normal" font="default" size="100%">4</style></issue><section><style face="normal" font="default" size="100%">149-162</style></section></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Song, J.

We show that this photoresponse does not arise from a heating effect, but that it is instead excellently described by a classical model of terahertz-induced gate-voltage rectification. This effect is distinct from the rectification mechanisms that have been studied previously, being determined by the phase-dependent interference of the source drain and gate voltage modulations induced by the terahertz field.

Determining the momentum relaxation time from a Drude model, the authors find a lower value than that from dc measurements, particularly at high frequencies/low temperatures. These deviations are consistent with the ratio tau(t)/tau(q,) where tau(q) is the full scattering time. This suggests that small-angle scattering leads to weaker heating of 2DEGs at low temperatures than expected from dc mobilit9y.

These collective large scale motions depend on global structure and thus will necessarily be perturbed by ligand binding events. We discuss the use of terahertz dielectric spectroscopy to measure these vibrational modes and the sensitivity of the technique to changes in protein conformation, oxidation state and environment. A challenge of applying this sensitivity as a spectroscopic assay for ligand binding is the sensitivity of the technique to both bulk water and water bound to the protein. This sensitivity can entirely obscure the signal from the protein or protein-ligand complex itself, thus necessitating sophisticated sample preparation making the technique impractical for industrial applications. We discuss methods to overcome this background and demonstrate how terahertz spectroscopy can be used to quickly assay protein binding for proteomics and pharmaceutical research.&lt;/p&gt;</style></abstract></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>10</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Knab, Joseph</style></author><author><style face="normal" font="default" size="100%">Shah, Binni</style></author><author><style face="normal" font="default" size="100%">Chen, Jing-Yin</style></author><author><style face="normal" font="default" size="100%">Markelz, Andrea</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Critical hydration and temperature effects on terahertz biomolecular sensing</style></title><secondary-title><style face="normal" font="default" size="100%">Chemical and Biological Standoff Detection III</style></secondary-title></titles><dates><year><style  face="normal" font="default" size="100%">2005</style></year></dates><publisher><style face="normal" font="default" size="100%">International Society for Optics and Photonics</style></publisher><volume><style face="normal" font="default" size="100%">5995</style></volume><pages><style face="normal" font="default" size="100%">59950P</style></pages><language><style face="normal" font="default" size="100%">eng</style></language></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Chen, J.

A strong absorbance and refractive index increase was observed with the oxidation. A simple phenomenological fitting using a continuous distribution of oscillators reproduces the frequency dependence of the complex dielectric response as well as demonstrates quantitative agreement with a uniform increase in either mode density or polarizability with oxidation in the 5-80 cm(-1) frequency range. Hydration dependence measurements find that a difference in the equilibrium water content for ferri and ferro cytochrome c is not sufficient to account for the large change in terahertz response. The large dielectric increase at terahertz frequencies with oxidation suggests either a significant global softening of the potential and/or a significant increase in polarizability with oxidation.&lt;/p&gt;</style></abstract><work-type><style face="normal" font="default" size="100%">Article</style></work-type><accession-num><style face="normal" font="default" size="100%">WOS:000232930600005</style></accession-num><notes><style face="normal" font="default" size="100%">ISI Document Delivery No.: 979GO&lt;br/&gt;Times Cited: 51&lt;br/&gt;Cited Reference Count: 29&lt;br/&gt;Cited References: &lt;br/&gt;     BERGHUIS AM, 1992, J MOL BIOL, V223, P959, DOI 10.1016/0022-2836(92)90255-I&lt;br/&gt;     BONE S, 1985, J MOL BIOL, V181, P323, DOI 10.1016/0022-2836(85)90096-8&lt;br/&gt;     BONE S, 1982, J MOL BIOL, V157, P571, DOI 10.1016/0022-2836(82)90477-6&lt;br/&gt;     BROOKS B, 1985, P NATL ACAD SCI USA, V82, P4995, DOI 10.1073/pnas.82.15.4995&lt;br/&gt;     Brucherseifer M, 2000, APPL PHYS LETT, V77, P4049, DOI 10.1063/1.1332415&lt;br/&gt;     Carlson HA, 2002, CURR OPIN CHEM BIOL, V6, P447, DOI 10.1016/S1367-5931(02)00341-1&lt;br/&gt;     CHEN JY, IN PRESS BIOPHYS J&lt;br/&gt;     CUSACK S, 1986, PHYSICA B &amp; C, V136, P256, DOI 10.1016/S0378-4363(86)80069-9&lt;br/&gt;     EDEN D, 1982, P NATL ACAD SCI-BIOL, V79, P815, DOI 10.1073/pnas.79.3.815&lt;br/&gt;     FROHWIRT EM, 1959, BIOPHYS J, V71, P570&lt;br/&gt;     Jackson J.D., 1975, CLASSICAL ELECTRODYN&lt;br/&gt;     KOPPENOL WH, 1982, J BIOL CHEM, V257, P4426&lt;br/&gt;     Kutteruf MR, 2003, CHEM PHYS LETT, V375, P337, DOI 10.1016/S0009-2614(03)00856-X&lt;br/&gt;     Markelz A, 2002, PHYS MED BIOL, V47, P3797, DOI 10.1088/0031-9155/47/21/318&lt;br/&gt;     Markelz AG, 2000, CHEM PHYS LETT, V320, P42, DOI 10.1016/S0009-2614(00)00227-X&lt;br/&gt;     Menikh A, 2004, BIOSENS BIOELECTRON, V20, P658, DOI 10.1016/j.bios.2004.03.006&lt;br/&gt;     Nagel M, 2002, APPL PHYS LETT, V80, P154, DOI 10.1063/1.1428619&lt;br/&gt;     PETHIG R, 1979, DIELECTRIC ELECTRONI&lt;br/&gt;     Qi PXR, 1996, BIOCHEMISTRY-US, V35, P12275, DOI 10.1021/bi961042w&lt;br/&gt;     RINGE D, 1985, PROG BIOPHYS MOL BIO, V45, P197, DOI 10.1016/0079-6107(85)90002-1&lt;br/&gt;     SHECHTER E, 1967, BIOPOLYMERS, V5, P788, DOI 10.1002/bip.1967.360050812&lt;br/&gt;     SIMONSON T, 1995, P NATL ACAD SCI USA, V92, P1082, DOI 10.1073/pnas.92.4.1082&lt;br/&gt;     SREENATHAN BR, 1971, BIOCHEM BIOPH RES CO, V42, P1122, DOI 10.1016/0006-291X(71)90021-0&lt;br/&gt;     Takano T., 1984, Methods and Applications in Crystallographic Computing.

Previously we have shown a strong contrast between the THz dielectric response for wild type (WT) and D96N mutant of bacteriorhodopsin. In those studies we observed a large increase in the THz absorbance of WT with excitation to thermally captured photo-intermediates whereas no such increase in absorbance was observed for the mutant D96N. These results suggest that the THz response is sensitive to structural changes and relative flexibility of biomolecules. However the photo-intermediate populations of the WT and D96N samples were not equivalent in those measurements. While the WT samples had relaxed (bR), M and P state intermediates present, the D96N samples had only bR and M states. Here we present terahertz absorbance measurements of D96N as a function of M and P state populations at room temperature. The THz response is constant for intermediate states populations up to 23% M state and up to 30% P state. These results verify that there is a fundamental difference in the conformational dynamics as measured by THz dielectric response for a single residue mutation.&lt;/p&gt;&lt;/div&gt;</style></abstract></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>10</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Markelz, A.

We find that these wells are strongly nonlinear at far-infrared frequencies: odd harmonics ninth order have been observed at high incident intensities, and the peak value of chi(3) reaches approximately 1 esu. This is several orders of magnitude larger than previously reported values for chi(3) in bulk n-GaAs (10(-4) esu)[1] and in polyacetylene (10(-7) esu)[2]. The large magnitude of chi(3) is attributed to the high carrier density in the InAs wells, and to the strong non-parabolicity of the conduction band in InAs. However, the free-carrier chi(3) for bulk InAs predicts a density-dependence different from that observed, and the measured decrease in chi(3) with increasing intensity indicates non-perturbative response. We find that the anisotropy of chi(3) displays the expected 4-fold symmetry.&lt;/p&gt;</style></abstract><accession-num><style face="normal" font="default" size="100%">WOS:A1994NE79600163</style></accession-num><notes><style face="normal" font="default" size="100%">Sherwin, Mark S/Q-4762-2017&lt;br/&gt;Sherwin, Mark S/0000-0002-3869-1893; Markelz, Andrea/0000-0003-0443-4319&lt;br/&gt;6th International Conference on Modulated Semiconductor Structures&lt;br/&gt;Aug 23-27, 1993&lt;br/&gt;Garmisch partenkir, germany&lt;br/&gt;Tech univ munchen, walter schottky inst&lt;br/&gt;9</style></notes></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Allen, S.

They have the most impact on terahertz science and technology that require a tunable, high power source to explore non-linear dynamics or that sacrifice incident power to recover the linear response of systems with very small cross-section. We describe three experiments that demonstrate the utility of these lasers in experiments on the terahertz dynamics of semiconductor nanostructures: (i) terahertz dynamics of resonant tunneling diodes, (ii) saturation spectroscopy of quantum wells and (iii) photon-assisted tunneling in superlattices.&lt;/p&gt;</style></abstract><accession-num><style face="normal" font="default" size="100%">WOS:A1994NR36100065</style></accession-num><notes><style face="normal" font="default" size="100%">Sherwin, Mark S/Q-4762-2017; Guimaraes, Paulo Sergio Soares/B-6918-2012&lt;br/&gt;Sherwin, Mark S/0000-0002-3869-1893; Guimaraes, Paulo Sergio Soares/0000-0002-0113-2641; Markelz, Andrea/0000-0003-0443-4319&lt;br/&gt;1993 International Conference on Luminescence (ICL 93)&lt;br/&gt;Aug 09-13, 1993&lt;br/&gt;Univ connecticut, storrs, ct&lt;br/&gt;Univ connecticut; opt soc amer; amer phys soc; ieee, laser &amp; electro opt soc; int union pure &amp; appl phys; int sci fdn; univ connecticut res fdn&lt;br/&gt;3</style></notes></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Markelz, A.

We find that the transmission of the fundamental, and the samples&#039; DC conductivity, decrease with increasing incident intensity, indicating a large rise in the scattering rate. Using the intensity-dependent transmission to account for absorption in the sample is not sufficient to recover a cubic power law for the third-harmonic intensity. In addition, given the increased scattering rate indicated by the conductivity data, the bulk free-carrier chi(3) due to non-parabolicity should decrease dramatically with increasing fundamental intensity, contrary to our results. Thus, non-parabolicity alone cannot account for the observed third-harmonic response.&lt;/p&gt;</style></abstract><accession-num><style face="normal" font="default" size="100%">WOS:A1994NM75300063</style></accession-num><notes><style face="normal" font="default" size="100%">Sherwin, Mark S/Q-4762-2017&lt;br/&gt;Sherwin, Mark S/0000-0002-3869-1893; Markelz, Andrea/0000-0003-0443-4319&lt;br/&gt;S&lt;br/&gt;8th International Conference on Hot Carriers in Semiconductors&lt;br/&gt;Aug 16-20, 1993&lt;br/&gt;Oxford univ, oxford, england&lt;br/&gt;Sci &amp; engn res council; royal soc; brit council; oxford univ&lt;br/&gt;4</style></notes></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Morris, D.
