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…
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…
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…
Josephson junctions, superconducting circuits, and qubit for quantum technologies
Roberta Citro, Claudio Guarcello, Sergio Pagano
In the realm of physics, a pivotal moment occurred six decades ago when Brian Josephson made a groundbreaking prediction, setting in motion a series of events that would eventually…
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…
Spin-orbital polarization of Majorana edge states in oxides nanowires
J. Settino, F. Forte, C. A. Perroni +3
We investigate a paradigmatic case of topological superconductivity in a one-dimensional nanowire with orbitals and a strong interplay of spin-orbital degrees of freedom due to…
Evolution of topological superconductivity by orbital selective confinement in oxide nanowires
C. A. Perroni, V. Cataudella, M. Salluzzo +2
We determine the optimal conditions to achieve topological superconducting phases having spin-singlet pairing for a planar nanowire with finite lateral width in the presence of an…
Minimal model of point contact Andreev reflection spectroscopy of multiband superconductors
F. Romeo, R. Citro
We formulate a minimal model of point contact Andreev reflection spectroscopy of a normal- metal/multiband superconductor interface. The theory generalizes the Blonder-Tinkham-Klap…
