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…
Boltzmann electronic dc transport in multiorbital weakly-disordered crystals
Marco Marciani, Lara Benfatto
Motivated by the increasing number of systems featuring multiple bands at low energy, we address the Boltzmann approach to transport in a multiband weakly disordered noninteracting…
Stabilizing spin systems via symmetrically tailored RKKY interactions
Jan Hermenau, Sascha Brinker, Marco Marciani +5
The spin of a single atom adsorbed on a substrate is a promising building block for future spintronics and quantum computation schemes. To process spin information and also for inc…
General scheme for stable single and multiatom nanomagnets according to symmetry selection rules
M. Marciani, C. Hübner, B. Baxevanis
At low temperature, information can be stored in the orientation of the localized magnetic moment of an adatom. However, scattering of electrons and phonons with the nanomagnet lea…
Effect of a tunnel barrier on the scattering from a Majorana bound state in an Andreev billiard
M. Marciani, H. Schomerus, C. W. J. Beenakker
We calculate the joint distribution of the scattering matrix and time-delay matrix of a chaotic quantum dot coupled by point contacts to me…
Effect of chiral symmetry on chaotic scattering from Majorana zero modes
H. Schomerus, M. Marciani, C. W. J. Beenakker
In many of the experimental systems that may host Majorana zero modes, a so-called chiral symmetry exists that protects overlapping zero modes from splitting up. This symmetry is o…
Time-delay matrix, midgap spectral peak, and thermopower of an Andreev billiard
M. Marciani, P. W. Brouwer, C. W. J. Beenakker
We derive the statistics of the time-delay matrix (energy derivative of the scattering matrix) in an ensemble of superconducting quantum dots with chaotic scattering (Andreev billi…
