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.
