Non-Equilibrium RKKY Interaction in Irradiated Graphene
Modi Ke, Mahmoud M. Asmar, Wang-Kong Tse
We demonstrate that the Ruderman-Kittel-Kasuya-Yosida (RKKY) interaction in graphene can be strongly modified by a time-periodic driving field even in the weak drive regime. This e…

Electron-Hole Asymmetry of Surface States in Topological Insulator Sb2Te3 Thin Films Revealed by Magneto-Infrared Spectroscopy
Yuxuan Jiang, Mahmoud M. Asmar, Xingyue Han +7
When surface states (SSs) form in topological insulators (TIs), they inherit the properties of bulk bands, including the electron-hole (e-h) asymmetry but with much more profound i…

Floquet Control of Indirect Exchange Interaction in Periodically Driven Two-Dimensional Electron Systems
Mahmoud M. Asmar, Wang-Kong Tse
We present a theory for the Ruderman-Kittel-Kasuya-Yosida (RKKY) interaction mediated by a two-dimensional (2D) electron system subjected to periodic driving. This is demonstrated…
