Onset of surface superconductivity beyond the Saint-James-de Gennes limit
Hong-Yi Xie, Vladimir G. Kogan, Maxim Khodas +1
We revisit the problem of the surface superconductivity nucleation focusing on the detailed study of the critical field as a function of temperature and disorder. Using th…
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…
Multifield Stochastic Particle Production: Beyond a Maximum Entropy Ansatz
Mustafa A. Amin, Marcos A. G. Garcia, Hong-Yi Xie +1
We explore non-adiabatic particle production for coupled scalar fields in a time-dependent background with stochastically varying effective masses, cross-couplings and…
