Landau levels and shallow donor states in GaAs/AlGaAs multiple quantum wells at mega-gauss magnetic fields
M. Zybert, M. Marchewka, E. M. Sheregii +8
Landau levels and shallow donor states in multiple GaAs/AlGaAs quantum wells (MQWs) are investigated by means of the cyclotron resonance at mega-gauss magnetic fields. Measurements…
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…
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…
THz response and colossal Kerr rotation from the surface states of the topological insulator BiSe
R. Valdés Aguilar, A. V. Stier, W. Liu +8
Ordered states of matter are typically categorized by their broken symmetries. With the ordering of spins in a ferromagnet or the freezing of a liquid into a solid, the loss of sym…
