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…
Self-consistent surface superconductivity in time-reversal symmetric Weyl semimetals
Mattia Trama, Viktor Könye, Ion Cosma Fulga +1
Weyl semimetals host topologically protected surface states, the so-called Fermi arcs, that have a penetration depth into the bulk that depends on surface-momentum, and diverges at…
Probing Topological Superconductivity of oxide nanojunctions using fractional Shapiro steps
Claudio Guarcello, Alfonso Maiellaro, Jacopo Settino +4
We theoretically discuss the emergence of fractional Shapiro steps in a Josephson junction created by confining a two-dimensional electron gas at an oxide interface. This phenomeno…
Dirac-like fermions anomalous magneto-transport in a spin-polarized oxide two-dimensional electron system
Yu Chen, Maria D'Antuono, Mattia Trama +8
In two-dimensional electron systems (2DES) the breaking of the inversion, time-reversal and bulk crystal-field symmetries is interlaced with the effects of spin-orbit coupling (SOC…
Engineered Josephson diode effect in kinked Rashba nanochannels
Alfonso Maiellaro, Mattia Trama, Jacopo Settino +3
The superconducting diode effect, reminiscent of the unidirectional charge transport in semiconductor diodes, is characterized by a nonreciprocal, dissipationless flow of Cooper pa…
