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…
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…
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…
Bardeen-Cooper-Schrieffer interaction as an infinite-range Penson-Kolb pairing mechanism
Francesco Romeo, Alfonso Maiellaro
We demonstrate that the well-known Bardeen-Cooper-Schrieffer interaction, when considered in real space, is equivalent to an infinite-range Penson-Kolb…
