Charge and spin qubits in interacting quantum dots coupled to Rashba-active leads
Grazia Di Bello, Fabrizio Pavan, Mattia Trama +3
We present a unified study of charge and spin qubits encoded in a single interacting quantum dot tunnel-coupled to Rashba fermionic leads. The dot is described by an Anderson impur…
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…
Magnetically Induced Switching-Current Jumps in InAs/Al Josephson Junctions
Ofelia Durante, Roberta Citro, Elia Strambini +8
We report Barkhausen-like switching at millitesla fields in an -doped InAs/Al nanowire Josephson junction, which serves as an interferometric probe of intrinsic magnetic reconfi…
Spin Hall and Edelstein effects in a ballistic quantum dot with Rashba spin-orbit coupling
Alfonso Maiellaro, Francesco Romeo, Mattia Trama +11
We study spin-resolved transport in a ballistic quantum dot with Rashba spin-orbit coupling, focusing on charge-to-spin conversion and spin Hall effect. In the regime where the dot…
Inhomogeneous superconductivity in (001), (110), and (111) KTaO two-dimensional electronic gases: effect of electronic confinement on the transition temperature
Mattia Trama, Roberta Citro, Carmine Antonio Perroni
Experimental observations on KTaO superconductivity report widely different critical temperatures with a clear hierarchy among different crystallographic orientations. Accounti…
Boltzmann theory of the inverse Edelstein effect in a two-dimensional Rashba gas
Irene Gaiardoni, Mattia Trama, Alfonso Maiellaro +3
We investigate the inverse Edelstein effect in a non-homogeneous system consisting of a ferromagnetic layer coupled to a Rashba two-dimensional electron gas. Within a semiclassical…
