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…
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…
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 $G…
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)…
Contribution of Collective Excitations to Third Harmonic Generation in Multiband Superconductors: the case of MgB
Jacopo Fiore, Mattia Udina, Marco Marciani +2
Multiband superconductors can host collective excitations with marked differences with respect to their single-band counterpart. We first study the spectrum of collective amplitude…
Resistivity anisotropy from the multiorbital Boltzmann equation in nematic FeSe
Marco Marciani, Lara Benfatto
We compute the resistivity anisotropy in the nematic phase of FeSe from the static solution of the multiorbital Boltzmann equation. By introducing disorder at the level of the micr…
