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…
Non-linear anomalous Edelstein response at altermagnetic interfaces
Mattia Trama, Irene Gaiardoni, Claudio Guarcello +5
In altermagnets, time-reversal symmetry breaking spin-polarizes electronic states, while total magnetization remains zero. In addition, at altermagnetic surfaces Rashba-spin orbit…
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…
Theory of charge-to-spin conversion under quantum confinement
Alfonso Maiellaro, Francesco Romeo, Mattia Trama +6
The interplay between spin and charge degrees of freedom in low-dimensional systems is a cornerstone of modern spintronics, where achieving all-electrical control of spin currents…
