Proximity effect in gap-asymmetric superconducting bilayers and regularization of transition rates
G. Marchegiani, G. Catelani
The standard mean-field treatment of low-temperature superconductors leads to a square-root divergent density of states at the gap value. This feature can lead to unphysical logari…
Excess quasiparticles and their dynamics in the presence of subgap states
P. B. Fischer, G. Catelani
Material inhomogeneities in a superconductor generically lead to broadening of the density of states and to subgap states. The latter are associated with spatial fluctuations of th…
Diode effect in the Fraunhofer pattern of disordered planar Josephson junctions
Luca Chirolli, Angelo Greco, Alessandro Crippa +4
The Josephson diode effect describes the property of a Josephson junction to have different values of the critical current for different direction of applied bias current and it is…
Nonequilibrium regimes for quasiparticles in superconducting qubits with gap-asymmetric junctions
G. Marchegiani, G. Catelani
Superconducting qubits hold promise for quantum computing, but their operation is challenged by various sources of noise, including excitations known as quasiparticles. Qubits with…
Predicting topological invariants and unconventional superconducting pairing from density of states and machine learning
Flavio Noronha, Askery Canabarro, Rafael Chaves +1
Competition between magnetism and superconductivity can lead to unconventional and topological superconductivity. However, the experimental confirmation of the presence of Majorana…
Spin and orbital Edelstein effect in spin-orbit coupled noncentrosymmetric superconductor
Satoshi Ando, Yukio Tanaka, Mario Cuoco +2
Superconductors without inversion symmetry can exhibit a non-zero magnetization when a supercurrent is present, leading to non-dissipative magnetoelectric effects. Here, we focus o…
