Photogalvanic Effects in Surface States of Topological Insulators under Perpendicular Magnetic Fields
Haoyu Li, Kainan Chang, Wang-Kong Tse +1
We present a theoretical study of the nonlinear magneto-optical shift conductivity in the surface states of the prototypical topological insulator BiSe under a perpendicula…
Theory of Tunneling between Two-Dimensional Electron Layers Driven by Spin Pumping: Adiabatic Regime and Beyond
Modi Ke, Mahmoud M. Asmar, Wang-Kong Tse
Tunneling spectroscopy between parallel two-dimensional (2D) electronic systems provides a powerful method to probe the underlying electronic properties by measuring tunneling cond…
Tunable Non-Equilibrium Magic and Minimum Twist Angles in AA-Stacked Twisted Multilayer Graphene
Yantao Li, Wang-Kong Tse
We report the discovery of a series of non-equilibrium magic angles at which isolated topological flat quasienergy bands form in AA-stacked twisted multilayer graphene under circul…
Second Harmonic Generation in Topological Insulators under Quantizing Magnetic Fields
Kainan Chang, Muhammad Zubair, Jin Luo Cheng +1
We theoretically investigate the second harmonic generation (SHG) of topological insulator surface states in a perpendicular magnetic field. Our theory is based on the microscopic…
