Supercurrent from the imaginary part of the Andreev levels in non-Hermitian Josephson junctions
Roberto Capecelatro, Marco Marciani, Gabriele Campagnano +2
We investigate the electronic transport properties of a superconductor-quantum dot-superconductor Josephson junction coupled to a ferromagnetic metal reservoir in the presence of a…
transitions in non-Hermitian magnetic Josephson junctions
Roberto Capecelatro, Marco Marciani, Claudio Guarcello +3
We study the transport properties of non-Hermitian magnetic Josephson junctions, considering a superconductor-quantum dot-superconductor device coupled to a ferromagnetic metallic…
Translation Groups for arbitrary Gauge Fields in Synthetic Crystals with real hopping amplitudes
Marco Marciani
The Cayley-crystals introduced in [F. R. Lux and E. Prodan, Annales Henri Poincaré 25(8), 3563 (2024)] are a class of lattices endowed with a Hamiltonian whose translation group $…
Andreev non-Hermitian Hamiltonian for open Josephson junctions from Green's functions
Roberto Capecelatro, Marco Marciani, Gabriele Campagnano +1
We investigate the transport properties of open Josephson junctions (JJs) through a minimal effective non-Hermitian (NH) approach derived from the equilibrium Green's function (GF)…
