Enhancement of stability of metastable states in the presence of Lévy noise
A. A. Dubkov, C. Guarcello, B. Spagnolo
The barrier-crossing event for superdiffusion characterized by symmetric Lévy flights is analyzed. Starting from the fractional Fokker-Planck equation, we derive an integro-differe…
Design and simulation of a transmon qubit chip for Axion detection
Roberto Moretti, Hervè Atsè Corti, Danilo Labranca +54
Quantum Sensing is a rapidly expanding research field that finds one of its applications in Fundamental Physics, as the search for Dark Matter. Devices based on superconducting qub…
Axion field influence on Josephson junction quasipotential
Roberto Grimaudo, Davide Valenti, Bernardo Spagnolo +3
The direct effect of an axion field on Josephson junctions is analyzed through the consequences on the effective potential barrier that prevents the junction from switching from th…
Noise-induced, ac-stabilized sine-Gordon breathers: Emergence and statistics
Duilio De Santis, Claudio Guarcello, Bernardo Spagnolo +2
Noisy and ac forcing can cooperatively lead to the emergence of sine-Gordon breathers robust to dissipation. This phenomenon is studied, for both Neumann and periodic boundary cond…
Heat-transfer fingerprint of Josephson breathers
Duilio De Santis, Bernardo Spagnolo, Angelo Carollo +2
A sine-Gordon breather enhances the heat transfer in a thermally biased long Josephson junction. This solitonic channel allows for the tailoring of the local temperature throughout…
ac-locking of thermally-induced sine-Gordon breathers
Duilio De Santis, Claudio Guarcello, Bernardo Spagnolo +2
A complete framework for exciting and detecting thermally-induced, stabilized sine-Gordon breathers in ac-driven long Josephson junctions is developed. The formation of long-time s…
