Fluctuational Anomalous Hall and Nernst Effects in Superconductors
Songci Li, Alex Levchenko
In this work we develop microscopic kinetic theory of the anomalous Hall and Nernst effects in superconductors induced by fluctuations in the vicinity of the critical transition te…
Fluctuation-driven thermal transport in graphene double-layers at charge neutrality
Alex Levchenko, Songci Li, A. V. Andreev
We develop a theory of fluctuation-driven phenomena in thermal transport in graphene double-layers. We work in the regime of electron hydrodynamics and focus on the double charge n…
Resonant second harmonic generation in a two-dimensional electron system
Maxim Dzero, Jaglul Hasan, Alex Levchenko
We consider the nonlinear response of a disordered two-dimensional electronic system, lacking inversion symmetry, to an external alternating electric field. The application of an i…
Quantum kinetics of anomalous and nonlinear Hall effects in topological semimetals
Elio J. König, Alex Levchenko
We present a systematic microscopic derivation of the semiclassical Boltzmann equation for band structures with the finite Berry curvature based on Keldysh technique of nonequilibr…
Transport in partially equilibrated inhomogeneous quantum wires
Alex Levchenko, Tobias Micklitz, Jerome Rech +1
We study transport properties of weakly interacting one-dimensional electron systems including on an equal footing thermal equilibration due to three-particle collisions and the ef…
Optical conductivity of a metal near an Ising-nematic quantum critical point
Songci Li, Prachi Sharma, Alex Levchenko +1
We study the optical conductivity of a pristine two-dimensional electron system near an Ising-nematic quantum critical point. We discuss the relation between the frequency scaling…
