Revealing electron-lattice decoupling by Peltier thermometry and nanoscale thermal imaging in graphene
Saurabh Kumar Srivastav, Tobias Völkl, Gary Quaresima +7
Electrical currents in low-dimensional quantum materials can drive electrons far from equilibrium, creating stark imbalance between electron and lattice temperatures. Yet, no exist…

Magnetochiral anisotropy on a quantum spin Hall edge
Youjian Chen, Gary Quaresima, Wenjin Zhao +3
We develop a theory of nonlinear low-magnetic-field magnetotransport on a helical edge of a quantum spin Hall insulator due to the edge state coupling to bulk midgap states. We foc…

Anomaly-induced sound absorption in Weyl semimetals
Ohad Antebi, D. A. Pesin, A. V. Andreev +1
We develop a semiclassical theory of sound absorption in Weyl semimetals in magnetic fields. We focus on the contribution to the absorption that stems from the existence of Berry m…
