Extrinsic quantum geometry in the quadrupolar bulk photovoltaic effect
Steven Gassner, Swati Chaudhary, Martin Claassen
The bulk photovoltaic effect has become a valuable probe of the quantum geometry of Bloch bands. While it is restricted to inversion-broken systems within the dipole approximation,…

Light-induced pseudo-magnetic fields in three-dimensional topological semimetals
Arpit Raj, Swati Chaudhary, Martin Rodriguez-Vega +3
In this work, we show that suitably designed spatially varying linearly polarized light provides a versatile route to generate and control pseudo-magnetic fields in Weyl semimetals…

Giant Shift Current in Electrically-Tunable Superlattice Bilayer Graphene
Nabil Atlam, Swati Chaudhary, Arpit Raj +4
Recent introduction of superlattice potentials has opened new avenues for engineering tunable electronic band structures featuring topologically nontrivial moiré-like bands. Here w…
