General nonlinear Hall current in magnetic insulators beyond the quantum anomalous Hall effect
Daniel Kaplan, Tobias Holder, Binghai Yan
Can a generic magnetic insulator exhibit a Hall current? The quantum anomalous Hall effect (QAHE) is one example of an insulating bulk carrying a quantized Hall conductivity and ot…
Twisted photovoltaics at terahertz frequencies from momentum shift current
Daniel Kaplan, Tobias Holder, Binghai Yan
The bulk photovoltaic effect (BPVE) converts light into a coherent dc current at zero bias, through what is commonly known as the shift current. This current has previously been at…
Nonvanishing sub-gap photocurrent as a probe of lifetime effects
Daniel Kaplan, Tobias Holder, Binghai Yan
For semiconductors and insulators, it is commonly believed that in-gap transitions into non-localized states are smoothly suppressed in the clean limit, i.e. at zero temperature th…
Consequences of Time-reversal-symmetry Breaking in the Light-Matter Interaction: Berry Curvature, Quantum Metric and Diabatic Motion
Tobias Holder, Daniel Kaplan, Binghai Yan
Nonlinear optical response is well studied in the context of semiconductors and has gained a renaissance in studies of topological materials in the recent decade. So far it mainly…
