Dissipative dynamics in a quantum bistable system: Crossover from weak to strong damping
Luca Magazzù, Davide Valenti, Bernardo Spagnolo +1
The dissipative dynamics of a quantum bistable system coupled to a Ohmic heat bath is investigated beyond the spin-boson approximation. Within the path-integral approach to quantum…
Phase dynamics in graphene-based Josephson junctions in the presence of thermal and correlated fluctuations
Claudio Guarcello, Davide Valenti, Bernardo Spagnolo
In this work we study by numerical methods the phase dynamics in ballistic graphene-based short Josephson junctions. The supercurrent through a graphene junction shows a non-sinuso…
Enhancement of the lifetime of metastable states in Er-doped Si nanocrystals by external coloured noise
Stefano Spezia, Davide Valenti, Dominique Persano Adorno +1
The changes in the lifetime of a metastable energy level in Er-doped Si nanocrystals in the presence of an external source of colored noise are analyzed for different values of noi…
Switching times in long-overlap Josephson junctions subject to thermal fluctuations and non-Gaussian noise sources
Davide Valenti, Claudio Guarcello, Bernardo Spagnolo
We investigate the superconducting lifetime of long current-biased Josephson junctions, in the presence of Gaussian and non-Gaussian noise sources. In particular, we analyze the dy…
