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.

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.
