Magnetochiral anisotropy of thermally activated phase slips in noncentrosymmetric superconductors
Alex Levchenko
Resistive tails of narrow superconducting wires below the critical temperature are governed by phase slips, thermally activated near the transition and quantum at lower temperature…
Effect of superconducting fluctuations on nonreciprocal dichroism and gyrotropy
Alex Levchenko
We study the spatially dispersive conductivity of a two-dimensional noncentrosymmetric superconductor, demonstrating that it acquires a nonreciprocal, odd-in-wavevector component f…
Non-Abelian monopoles in the multiterminal Josephson effect
Hong-Yi Xie, Jaglul Hasan, Alex Levchenko
In this work we present a detailed theoretical analysis for the spectral properties of Andreev bound states in the multiterminal Josephson junctions by employing a symmetry-constra…
Topological supercurrents interaction and fluctuations in the multiterminal Josephson effect
Hong-Yi Xie, Alex Levchenko
We study the Josephson effect in the multiterminal junction of topological superconductors. We use the symmetry-constrained scattering matrix approach to derive band dispersions of…
Weyl nodes in Andreev spectra of multiterminal Josephson junctions: Chern numbers, conductances and supercurrents
Hong-Yi Xie, Maxim G. Vavilov, Alex Levchenko
We consider mesoscopic four-terminal Josephson junctions and study emergent topological properties of the Andreev subgap bands. We use symmetry-constrained analysis for Wigner-Dyso…
