The apparatus includes an emitter configured to emit a THz pulse and a detector configured to detect the THz pulse after the pulse is transmitted through a sample disposed on a sample surface of the detector. A pulsed radiation generator generates a probe beam to interrogate the detector. The detector may include an electro-optical (“EO”) crystal configured to change in birefringence according to the THz pulse. The sample surface of the detector may have a dielectric coating which is transmissive to THz and reflective to the probe beam. The sample is disposed on the dielectric coating.&lt;/div&gt;

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.

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.

From cellular communication through membrane ion channels to oxygen uptake and delivery by haemoglobin, structural changes are critical. It has been suggested that vibrations that extend through the protein play a crucial role in controlling these structural changes. While nature may utilize such long-range vibrations for optimization of biological processes, bench-top characterization of these extended structural motions for engineered biochemistry has been elusive. Here we show the first optical observation of long-range protein vibrational modes. This is achieved by orientation-sensitive terahertz near-field microscopy measurements of chicken egg white lysozyme single crystals. Underdamped modes are found to exist for frequencies &amp;gt;10 cm(-1). The existence of these persisting motions indicates that damping and intermode coupling are weaker than previously assumed. The methodology developed permits protein engineering based on dynamical network optimization.&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:000331084200018</style></accession-num><notes><style face="normal" font="default" size="100%">ISI Document Delivery No.: AA4RQ&lt;br/&gt;Times Cited: 101&lt;br/&gt;Cited Reference Count: 48&lt;br/&gt;Cited References: &lt;br/&gt;     AUSTIN RH, 1989, PHYS REV LETT, V62, P1912, DOI 10.1103/PhysRevLett.62.1912&lt;br/&gt;     Bahar I, 2005, CURR OPIN STRUC BIOL, V15, P586, DOI 10.1016/j.sbi.2005.08.007&lt;br/&gt;     Balabin IA, 2000, SCIENCE, V290, P114, DOI 10.1126/science.290.5489.114&lt;br/&gt;     Balog E, 2004, PHYS REV LETT, V93, DOI 10.1103/PhysRevLett.93.028103&lt;br/&gt;     Barth A, 2002, Q REV BIOPHYS, V35, P369, DOI 10.1017/S0033583502003815&lt;br/&gt;     Benkovic SJ, 2003, SCIENCE, V301, P1196, DOI 10.1126/science.1085515&lt;br/&gt;     Brooks BR, 2009, J COMPUT CHEM, V30, P1545, DOI 10.1002/jcc.21287&lt;br/&gt;     BROOKS BR, 1983, J COMPUT CHEM, V4, P187, DOI 10.1002/jcc.540040211&lt;br/&gt;     Brooks CL, 1988, PROTEINS THEORETICAL&lt;br/&gt;     Chen JY, 2007, APPL PHYS LETT, V90, DOI 10.1063/1.2748852&lt;br/&gt;     Chen JY, 2005, PHYS REV E, V72, DOI 10.1103/PhysRevE.72.040901&lt;br/&gt;     Ding T, 2012, VIB SPECTROSC, V61, P144, DOI 10.1016/j.vibspec.2012.02.020&lt;br/&gt;     GENZEL L, 1976, BIOPOLYMERS, V15, P219, DOI 10.1002/bip.1976.360150115&lt;br/&gt;     George DK, 2013, IEEE T THZ SCI TECHN, V3, P288, DOI 10.1109/TTHZ.2013.2256233&lt;br/&gt;     GRISCHKOWSKY D, 1990, J OPT SOC AM B, V7, P2006, DOI 10.1364/JOSAB.7.002006&lt;br/&gt;     Hafner J, 2011, J CHEM PHYS, V135, DOI 10.1063/1.3646312&lt;br/&gt;     Hammes GG, 2002, BIOCHEMISTRY-US, V41, P8221, DOI 10.1021/bi0260839&lt;br/&gt;     He YF, 2011, BIOPHYS J, V100, P1058, DOI 10.1016/j.bpj.2010.12.3731&lt;br/&gt;     KACHALOVA GS, 1991, FEBS LETT, V284, P91, DOI 10.1016/0014-5793(91)80769-Y&lt;br/&gt;     Karplus M, 2005, P NATL ACAD SCI USA, V102, P6679, DOI 10.1073/pnas.0408930102&lt;br/&gt;     Knab J, 2006, BIOPHYS J, V90, P2576, DOI 10.1529/biophysj.105.069088&lt;br/&gt;     Knab JR, 2010, APPL PHYS LETT, V97, DOI 10.1063/1.3467192&lt;br/&gt;     LEVY RM, 1984, J PHYS CHEM-US, V88, P4233, DOI 10.1021/j150663a009&lt;br/&gt;     Lipps F, 2012, PHYS CHEM CHEM PHYS, V14, P6375, DOI 10.1039/c2cp23760a&lt;br/&gt;     Liu D, 2008, PHYS REV LETT, V101, DOI 10.1103/PhysRevLett.101.135501&lt;br/&gt;     MacKerell AD, 1998, J PHYS CHEM B, V102, P3586, DOI 10.1021/jp973084f&lt;br/&gt;     Markelz AG, 2008, IEEE J SEL TOP QUANT, V14, P180, DOI 10.1109/JSTQE.2007.913424&lt;br/&gt;     Meinhold L, 2007, PHYS REV LETT, V99, DOI 10.1103/PhysRevLett.99.138101&lt;br/&gt;     Meinhold L, 2007, PROTEINS, V66, P941, DOI 10.1002/prot.21246&lt;br/&gt;     Mittleman D.M., 2003, SENSING TERAHERTZ RA&lt;br/&gt;     MOELLER KD, 1992, BIOPHYS J, V61, P276, DOI 10.1016/S0006-3495(92)81834-9&lt;br/&gt;     Perutz MF, 1998, ANNU REV BIOPH BIOM, V27, P1, DOI 10.1146/annurev.biophys.27.1.1&lt;br/&gt;     Planken PCM, 2011, J INFRARED MILLIM TE, V32, P975, DOI 10.1007/s10762-011-9824-3&lt;br/&gt;     Rheinstadter MC, 2009, PHYS REV LETT, V103, DOI 10.1103/PhysRevLett.103.128104&lt;br/&gt;     Sakai K., 2005, TERAHERTZ OPTOELECTR&lt;br/&gt;     Schumacher M, 2002, NATURE, V417, P501, DOI 10.1038/417501a&lt;br/&gt;     Siegrist K, 2006, J AM CHEM SOC, V128, P5764, DOI 10.1021/ja058176u&lt;br/&gt;     Singh R, 2012, J PHYS CHEM A, V116, P10359, DOI 10.1021/jp307288r&lt;br/&gt;     SMITH J, 1990, J CHEM PHYS, V93, P2974, DOI 10.1063/1.458885&lt;br/&gt;     SMITH JC, 1991, Q REV BIOPHYS, V24, P227, DOI 10.1017/S0033583500003723&lt;br/&gt;     TEETER MM, 1990, J PHYS CHEM-US, V94, P8091, DOI 10.1021/j100384a021&lt;br/&gt;     TIDOR B, 1994, J MOL BIOL, V238, P405, DOI 10.1006/jmbi.1994.1300&lt;br/&gt;     Tych KM, 2011, J APPL CRYSTALLOGR, V44, P129, DOI 10.1107/S0021889810043372&lt;br/&gt;     Urabe H, 1998, BIOPHYS J, V74, P1533, DOI 10.1016/S0006-3495(98)77865-8&lt;br/&gt;     Walther M, 2003, CHEM PHYS, V288, P261, DOI 10.1016/S0301-0104(03)00031-4&lt;br/&gt;     WU Q, 1995, APPL PHYS LETT, V67, P3523, DOI 10.1063/1.114909&lt;br/&gt;     Xie AH, 2002, PHYS REV LETT, V88, DOI 10.1103/PhysRevLett.88.018102&lt;br/&gt;     Xu J, 2006, J PHYS CHEM B, V110, P24255, DOI 10.1021/jp064830w&lt;br/&gt;Acbas, Gheorghe Niessen, Katherine A.

At low frequencies, transport is essentially thickness independent showing the dominant contribution of the surface electrons. Despite their extended exposure to ambient conditions, these surfaces exhibit robust properties including narrow, almost thickness-independent Drude peaks, and an unprecedentedly large polarization rotation of linearly polarized light reflected in an applied magnetic field. This Kerr rotation can be as large as 65 degrees and can be explained by a cyclotron resonance effect of the surface states.&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:000300576000025</style></accession-num><notes><style face="normal" font="default" size="100%">ISI Document Delivery No.: 896NY&lt;br/&gt;Times Cited: 164&lt;br/&gt;Cited Reference Count: 35&lt;br/&gt;Cited References: &lt;br/&gt;     Akhmerov AR, 2009, PHYS REV LETT, V102, DOI 10.1103/PhysRevLett.102.216404&lt;br/&gt;     Alpichshev Z, 2010, PHYS REV LETT, V104, DOI 10.1103/PhysRevLett.104.016401&lt;br/&gt;     Analytis JG, 2010, PHYS REV B, V81, DOI 10.1103/PhysRevB.81.205407&lt;br/&gt;     Bansal N., ARXIV11045709&lt;br/&gt;     Benia HM, 2011, PHYS REV LETT, V107, DOI 10.1103/PhysRevLett.107.177602&lt;br/&gt;     Bianchi M, 2010, NAT COMMUN, V1, DOI 10.1038/ncomms1131&lt;br/&gt;     Butch NP, 2010, PHYS REV B, V81, DOI 10.1103/PhysRevB.81.241301&lt;br/&gt;     Chen J, 2011, PHYS REV B, V83, DOI 10.1103/PhysRevB.83.241304&lt;br/&gt;     Chen YL, 2009, SCIENCE, V325, P178, DOI 10.1126/science.1173034&lt;br/&gt;     Essin AM, 2009, PHYS REV LETT, V102, DOI 10.1103/PhysRevLett.102.146805&lt;br/&gt;     Eto K, 2010, PHYS REV B, V81, DOI 10.1103/PhysRevB.81.195309&lt;br/&gt;     Fu L, 2007, PHYS REV B, V76, DOI 10.1103/PhysRevB.76.045302&lt;br/&gt;     Fu L, 2008, PHYS REV LETT, V100, DOI 10.1103/PhysRevLett.100.096407&lt;br/&gt;     Hsieh D, 2008, NATURE, V452, P970, DOI 10.1038/nature06843&lt;br/&gt;     Hsieh D, 2009, NATURE, V460, P1101, DOI 10.1038/nature08234&lt;br/&gt;     Jenkins GS, 2010, PHYS REV B, V82, DOI 10.1103/PhysRevB.82.125120&lt;br/&gt;     King PDC, 2011, PHYS REV LETT, V107, DOI 10.1103/PhysRevLett.107.096802&lt;br/&gt;     LaForge AD, 2010, PHYS REV B, V81, DOI 10.1103/PhysRevB.81.125120&lt;br/&gt;     Lan YP, 2011, PHYS REV B, V83, DOI 10.1103/PhysRevB.83.205109&lt;br/&gt;     Maciejko J, 2010, PHYS REV LETT, V105, DOI 10.1103/PhysRevLett.105.166803&lt;br/&gt;     Moore JE, 2007, PHYS REV B, V75, DOI 10.1103/PhysRevB.75.121306&lt;br/&gt;     Qi XL, 2008, PHYS REV B, V78, DOI 10.1103/PhysRevB.78.195424&lt;br/&gt;     Qu DX, 2010, SCIENCE, V329, P821, DOI 10.1126/science.1189792&lt;br/&gt;     Roushan P, 2009, NATURE, V460, P1106, DOI 10.1038/nature08308&lt;br/&gt;     Roy R, 2009, PHYS REV B, V79, DOI 10.1103/PhysRevB.79.195322&lt;br/&gt;     Steinberg H, 2011, PHYS REV B, V84, DOI 10.1103/PhysRevB.84.233101&lt;br/&gt;     Sushkov AB, 2010, PHYS REV B, V82, DOI 10.1103/PhysRevB.82.125110&lt;br/&gt;     THOULESS DJ, 1982, PHYS REV LETT, V49, P405, DOI 10.1103/PhysRevLett.49.405&lt;br/&gt;     Tkachov G, 2011, PHYS REV B, V84, DOI 10.1103/PhysRevB.84.035405&lt;br/&gt;     Tse WK, 2010, PHYS REV B, V82, DOI 10.1103/PhysRevB.82.161104&lt;br/&gt;     Tse WK, 2010, PHYS REV LETT, V105, DOI 10.1103/PhysRevLett.105.057401&lt;br/&gt;     VONKLITZING K, 1980, PHYS REV LETT, V45, P494, DOI 10.1103/physrevlett.45.494&lt;br/&gt;     Xia Y, 2009, NAT PHYS, V5, P398, DOI 10.1038/NPHYS1274&lt;br/&gt;     Xiong J., PHYSICA A E IN PRESS&lt;br/&gt;     Zhang XA, 2010, PHYS REV B, V82, DOI 10.1103/PhysRevB.82.245107&lt;br/&gt;Aguilar, R.

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.

We find that the energy distribution can be characterized by an effective electron temperature, T-e(&amp;gt;T-L), that agrees well with values estimated from the THz-illuminated, dc conductivity. This agreement indicates that under strong THz drive, LO phonon scattering dominates both energy and momentum relaxation; that the carrier distribution maintains a heated, thermal form; and that phonon drift effects are negligible.

We analyse the dependence of sigma(DC) on E(omega) assuming that electron-optical phonon scattering dominates energy relaxation, that the absorbed power has a Drude form and that the electron distribution is thermal. This simple analysis is self-consistent: Arrhenius plots of the estimated energy loss rate have a slope near -homega(LO)BAR/k(B) for all frequencies, as expected for energy loss by optical phonon emission. We find that the effective energy relaxation time tau(epsilon) varies with the frequency of the applied field, from tau(epsilon) approximately 4 ps at 0.34 THz to tau(epsilon) approximately 0.3 ps at 3.45 THz. This may indicate a frequency-dependent form for the hot-phonon distribution.&lt;/p&gt;</style></abstract><accession-num><style face="normal" font="default" size="100%">WOS:A1994NM75300116</style></accession-num><notes><style face="normal" font="default" size="100%">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;2</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>10</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Sherwin, M.
