A sudden collapse in the transport lifetime across the topological phase transition in
Liang Wu, M. Brahlek, R. Valdés Aguilar +7
Topological insulators (TIs) are newly discovered states of matter with robust metallic surface states protected by the topological properties of the bulk wavefunctions. A quantum…
Polarization modulation time-domain terahertz polarimetry
C. M. Morris, R. Valdés Aguilar, A. V. Stier +1
We present high precision measurements of polarization rotations in the frequency range from 0.1 to 2.5 THz using a polarization modulation technique. A motorized stage rotates a p…
Aging and reduced bulk conductance in thin films of the topological insulator BiSe
R. Valdés Aguilar, L. Wu, A. V. Stier +5
We report on the effect of exposure to atmospheric conditions on the THz conductivity of thin films of the topological insulator BiSe. We find: 1) two contributions of mobi…
Low energy electrodynamics of the Kondo-lattice antiferromagnet CeCuGe
G. Bossé, L. S. Bilbro, R. Valdés Aguilar +6
We present time-domain THz spectroscopy data of a thin film of the Kondo-lattice antiferromagnet CeCuGe. The low frequency complex conductivity has been obtained down to te…
