Multilayer graphenes as a platform for interaction-driven physics and topological superconductivity
Areg Ghazaryan, Tobias Holder, Erez Berg +1
Motivated by the recent discoveries of superconductivity in bilayer and trilayer graphene, we theoretically investigate superconductivity and other interaction-driven phases in mul…
Unification of Nonlinear Anomalous Hall Effect and Nonreciprocal Magnetoresistance in Metals by the Quantum Geometry
Daniel Kaplan, Tobias Holder, Binghai Yan
The quantum geometry has significant consequences in determining transport and optical properties in quantum materials. Here, we use a semiclassical formalism coupled with perturba…
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…
Unifying semiclassics and quantum perturbation theory at nonlinear order
Daniel Kaplan, Tobias Holder, Binghai Yan
Nonlinear electrical response permits a unique window into effects of band structure geometry. It can be calculated either starting from a Boltzmann approach for small frequencies,…
Para-hydrodynamics from weak surface scattering in ultraclean thin flakes
Yotam Wolf, Amit Aharon-Steinberg, Binghai Yan +1
Electron hydrodynamics typically emerges in electron fluids with a high electron-electron collision rate. However, new experiments with thin flakes of WTe have revealed that ot…
Direct observation of vortices in an electron fluid
Amit Aharon-Steinberg, Tobias Völkl, Arkady Kaplan +12
Vortices are the hallmarks of hydrodynamic flow. Recent studies indicate that strongly-interacting electrons in ultrapure conductors can display signatures of hydrodynamic behavior…
