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…
Topological Andreev bands in three-terminal Josephson junctions
Hong-Yi Xie, Maxim G. Vavilov, Alex Levchenko
We study the emergent band topology of subgap Andreev bound states in the three-terminal Josephson junctions. We scrutinize the symmetry constraints of the scattering matrix in the…
Response theory of the ergodic many-body delocalized phase: Keldysh Finkel'stein sigma models and the 10-fold way
Yunxiang Liao, Alex Levchenko, Matthew S. Foster
We derive the finite temperature Keldysh response theory for interacting fermions in the presence of quenched disorder, as applicable to any of the 10 Altland-Zirnbauer classes in…
