Shift-current response as a probe of quantum geometry and electron-electron interactions in twisted bilayer graphene
Swati Chaudhary, Cyprian Lewandowski, Gil Refael
Moiré materials, and in particular twisted bilayer graphene (TBG), exhibit a range of fascinating phenomena, that emerge from the interplay of band topology and interactions. We sh…
Anomalous exciton transport in response to a uniform, in-plane electric field
Swati Chaudhary, Christina Knapp, Gil Refael
Excitons are neutral objects, that, naively, should have no response to a uniform, electric field. Could the Berry curvature of the underlying electronic bands alter this conclusio…
Controlling ligand-mediated exchange interactions in periodically driven magnetic materials
Swati Chaudhary, Alon Ron, David Hsieh +1
A periodic drive could alter the effective exchange interactions in magnetic materials. Here, we explore how exchange pathways affect the effective interactions of periodically dri…
Phonon-induced Floquet second-order topological phases protected by space-time symmetries
Swati Chaudhary, Arbel Haim, Yang Peng +1
The co-existence of spatial and non-spatial symmetries together with appropriate commutation/anticommutation relations between them can give rise to static higher-order topological…
Orbital Floquet Engineering of Exchange Interactions in Magnetic Materials
Swati Chaudhary, David Hsieh, Gil Refael
We present a new scheme to control the spin exchange interactions between two magnetic ions by manipulating the orbital degrees of freedom using a periodic drive. We discuss two di…
Berry-electrodynamics - Anomalous drift and pumping from time-dependent Berry connection
Swati Chaudhary, Manuel Endres, Gil Refael
The Berry curvature of a Bloch band can be interpreted as a local magnetic field in reciprocal space. This analogy can be extended by defining an electric field analog in reciproca…
