Breather dynamics in a stochastic sine-Gordon equation: evidence of noise-enhanced stability
Duilio De Santis, Claudio Guarcello, Bernardo Spagnolo +2
The dynamics of sine-Gordon breathers is studied in the presence of dissipative and stochastic perturbations. Taking a stationary breather with a random phase value as the initial…
Supratransmission-induced travelling breathers in long Josephson junctions
Duilio De Santis, Claudio Guarcello, Bernardo Spagnolo +2
The emergence of travelling sine-Gordon breathers due to the nonlinear supratransmission effect is theoretically studied in a long Josephson junction driven by suitable magnetic pu…
Axion-induced oscillations in Josephson qubits
Roberto Grimaudo, Claudio Guarcello, Giovanni Filatrella +2
An effective quantum description of the axion is proposed as a two-level dynamic system together with a spin-spin Hamiltonian for a coupled axion-Josephson qubit system. The intera…
Multiparameter quantum critical metrology
Giovanni Di Fresco, Bernardo Spagnolo, Davide Valenti +1
Single parameter estimation is known to benefit from extreme sensitivity to parameter changes in quantum critical systems. However, the simultaneous estimation of multiple paramete…
Generation of travelling sine-Gordon breathers in noisy long Josephson junctions
Duilio De Santis, Claudio Guarcello, Bernardo Spagnolo +2
The generation of travelling sine-Gordon breathers is achieved through the nonlinear supratransmission effect in a magnetically driven long Josephson junction, in the presence of l…
Josephson junction-based axion detection through resonant activation
Roberto Grimaudo, Davide Valenti, Bernardo Spagnolo +2
We discuss the resonant activation phenomenon on a Josephson junction due to the coupling of the Josephson system with axions. We show how such an effect can be exploited for axion…
