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.

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%">Chen, J.-Y.</style></author><author><style face="normal" font="default" size="100%">Cox, W.</style></author><author><style face="normal" font="default" size="100%">Bright, F.

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.
