Fluctuation-Induced Magnetoelectric Effect in Noncentrosymmetric Superconductors
Jaglul Hasan, Daniel Shaffer, Maxim Dzero +1
We study the effect of superconducting fluctuations on the spin susceptibility and NMR relaxation rate in noncentrosymmetric two-dimensional materials above the superconducting tra…
Electrical magnetochiral anisotropy in Rashba superconductors
Joaquim Telles de Miranda, Maxim Khodas, Alex Levchenko
We theoretically investigate the role of higher-order Lifshitz invariants in nonreciprocal charge transport in two-dimensional noncentrosymmetric superconductors with Rashba spin-o…
Magnetochiral anisotropy in strained superconducting transition metal dichalcogenides
Joaquim Telles de Miranda, Maxim Khodas, Alex Levchenko
We present a theoretical study of nonreciprocal charge transport in two-dimensional noncentrosymmetric superconductors, taking the transition-metal dichalcogenide MoS as a repr…
Nonlinear Hall effect in topological Dirac semimetals in parallel magnetic field
Maxim Dzero, Maxim Khodas, Alex Levchenko +1
We compute the second-harmonic response of two-dimensional topological Dirac semimetals subjected to an external in-plane magnetic field. The quantum kinetic equation for the Wigne…
Admittance and critical current of nonreciprocal Josephson junctions
Tony Liu, Alex Levchenko
We investigate the nonequilibrium current response in diffusive superconductor-normal-metal-superconductor junctions subjected to a low-frequency AC voltage. Using a kinetic descri…
Extrinsic anomalous Hall effect in altermagnets
A. Osin, A. Levchenko, M. Khodas
We find the extrinsic anomalous Hall conductivity (AHC) to be comparable to the intrinsic one in roughly half of the altermagnetic spin Laue groups in the limit of large exchange s…
