Suppression of timing errors in short overdamped Josephson junctions
Andrey L. Pankratov, Bernardo Spagnolo
The influence of fluctuations and periodical driving on temporal characteristics of short overdamped Josephson junction is analyzed. We obtain the standard deviation of the switchi…
Transient behavior of a population dynamical model
B. Spagnolo, D. Valenti, A. Fiasconaro
The transient behavior of an ecosystem with N random interacting species in the presence of a multiplicative noise is analyzed. The multiplicative noise mimics the interaction with…
Noise Enhanced Stability in Fluctuating Metastable States
Alexander A. Dubkov, Nikolay V. Agudov, Bernardo Spagnolo
We derive general equations for the nonlinear relaxation time of Brownian diffusion in randomly switching potential with a sink. For piece-wise linear dichotomously fluctuating pot…
Noise delayed decay of unstable states: theory versus numerical simulations
N. V. Agudov, R. Mannella, A. V. Safonov +1
We study the noise delayed decay of unstable nonequilibrium states in nonlinear dynamical systems within the framework of the overdamped Brownian motion model. We give the exact ex…
Langevin Approach to Understand the Noise of Microwave Transistors
F. Principato, B. Spagnolo, G. Ferrante +1
A Langevin approach to understand the noise of microwave devices is presented. The device is represented by its equivalent circuit with the internal noise sources included as stoch…
Noise Enhanced Stability
Bernardo Spagnolo, Nikolay V. Agudov, Alexander A. Dubkov
The noise can stabilize a fluctuating or a periodically driven metastable state in such a way that the system remains in this state for a longer time than in the absence of white n…
