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…
Majorana bound state parity exchanges in planar Josephson junctions
Varsha Subramanyan, Jukka I Vayrynen, Alex Levchenko +1
We describe a scheme to exchange fermion parity between two pairs of Majorana bound states mediated by coupling with a centralized quantum dot. We specifically formulate such a sch…
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…
Negative Viscosity and Eddy Flow of Imbalanced Electron-Hole Liquid in Graphene
Hong-Yi Xie, Alex Levchenko
We present a hydrodynamic theory for electron-hole magnetotransport in graphene incorporating carrier-population imbalance, energy, and momentum relaxation processes. We focus on t…
