Floquet engineering of topological bands in semiconductor van der Waals heterobilayers
Eréndira Santana-Suárez, Brayan E. Walteros-Mendivelso, A. Jazmín Tapia-de-la-Rosa +2
We show that periodic driving with near-infrared to visible light drives topological phase transitions in the photon-dressed band structure of transition-metal dichalcogenide heter…
Floquet Superlattices and Edge States in Graphene Nanoribbons
Siam Sarower, Jonathon Dvorscak, Nancy P. Sandler +1
Structured light provides a route to imprint spatially patterned Floquet potentials onto quantum materials. As a particular example, we study a zigzag graphene nanoribbon driven by…
Vortex-Beam-Driven Dirac Materials: Impurity and Polarization Effects on Light-Induced Vortex and Edge States
Trevor W. Walsh, Eric E. Caldwell, Nancy P. Sandler +1
We study impurity scattering and polarization detuning in finite-size vortex-light-beam-driven massive Dirac systems. In finite geometries, circularly polarized vortex light opens…
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…
Photo-induced Multiply Quantized Vortex States in Dirac-like Materials
Lauren I. Massaro, Connor Meese, Nancy P. Sandler +1
Subjecting a massive two-dimensional Dirac material to a vortex light beam provides a mechanism for the photo-induction of multiply quantized vortices. Using Floquet theory, we sho…
Floquet-driven indirect exchange interaction mediated by topological insulator surface states
Modi Ke, Mahmoud M. Asmar, Wang-Kong Tse
Light drives offer a potential tool for the dynamical control of magnetic interactions in matter. We theoretically investigate the indirect exchange coupling between two parallel c…
