Current-driven reduction of topological protection in multichannel superconductors
Alfonso Maiellaro
We investigate the robustness of topological phases in a Kitaev ladder composed of two coupled superconducting chains under the perturbing influence of a finite charge current. By…
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…
Edelstein Effect in Isotropic and Anisotropic Rashba Models
Irene Gaiardoni, Mattia Trama, Alfonso Maiellaro +3
We investigate spin-to-charge conversion via the Edelstein effect in a 2D Rashba electron gas using the semiclassical Boltzmann approach. We analyze the magnetization arising from…
