Analysis of Josephson junctions switching time distributions for the detection of single microwave photons
A. S. Piedjou Komnang, C. Guarcello, C. Barone +5
We investigate an optimal scheme for the detection of single microwave photons by a Josephson junction through the analysis of its switching times distribution. The proposed analys…
Detection of signals in presence of noise through Josephson junction switching currents
O. V. Pountougnigni, R. Yamapi, C. Tchawoua +2
Josephson junctions can be employed to reveal a sinusoidal signal in presence of Gaussian noise. To mimic realistic setups, the detection is performed linearly ramping the bias cur…
Parallel Simulation of Josephson Junctions With Multiplicative Noise
Vincenzo Pierro, Luigi Troiano, Elena Mejuto Villa +2
Parallel graphic processing units have been employed for fast simulations of the switching dynam- ics of Josephson junctions subject to critical current fluctuations. Such a system…
Annealing-induced grain coarsening and voltage kinks in superconducting NbRe films
Zahra Makhdoumi Kakhaki, Anton O. Pokusinskyi, Francesco Avitabile +5
NbRe, a non-centrosymmetric superconductor with a transition temperature up to 9\,K, attracts interest for its strong antisymmetric spin-orbit coupling and suitabili…
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…
