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…
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…
X-shaped and Y-shaped Andreev resonance profiles in a superconducting quantum dot
Shuo Mi, D. I. Pikulin, M. Marciani +1
The quasi-bound states of a superconducting quantum dot that is weakly coupled to a normal metal appear as resonances in the Andreev reflection probability, measured via the differ…
Leggett modes in iron-based superconductors as a probe of Time Reversal Symmetry Breaking
M. Marciani, L. Fanfarillo, C. Castellani +1
Since their discovery, it has been suggested that pairing in pnictides can be mediated by spin fluctuations between hole and electron bands. In this view, multiband superconductivi…
