Andreev spectroscopy of nonhelical spin textures in topological insulators
David J. Alspaugh, Mahmoud M. Asmar, Daniel E. Sheehy +1
We study how nonhelical spin textures affect the proximity-induced superconductivity of topological insulator (TI)-superconductor (SC) interface states. In particular we calculate…
Particle-hole asymmetry and quantum confinement effects on the magneto-optical response of topological insulator thin-films
Mahmoud M. Asmar, Gaurav Gupta, Wang-Kong Tse
Intrinsically broken symmetries in the bulk of topological insulators (TIs) are manifested in their surface states. In spite of particle-hole asymmetry in TIs, it has often been as…
Impurity Screening and Friedel Oscillations in Floquet-driven Two-dimensional Metals
Mahmoud M. Asmar, Wang-Kong Tse
We develop a theory for the non-equilibrium screening of a charged impurity in a two-dimensional electron system under a strong time-periodic drive. Our analysis of the time-averag…
