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…
Exact Results for Spectra of Overdamped Brownian Motion in Fixed and Randomly Switching Potentials
A. A. Dubkov, V. N. Ganin, B. Spagnolo
The exact formulae for spectra of equilibrium diffusion in a fixed bistable piecewise linear potential and in a randomly flipping monostable potential are derived. Our results are…
Noise in ecosystems: a short review
B. Spagnolo, D. Valenti, A. Fiasconaro
Noise, through its interaction with the nonlinearity of the living systems, can give rise to counter-intuitive phenomena such as stochastic resonance, noise-delayed extinction, tem…
Pattern formation and spatial correlation induced by the noise in two competing species
D. Valenti, A. Fiasconaro, B. Spagnolo
We analyze the spatio-temporal patterns of two competing species in the presence of two white noise sources: an additive noise acting on the interaction parameter and a multiplicat…
Enhancement of the escape time in metastable states with colored noise
A. Fiasconaro, D. Valenti, B. Spagnolo
We present a study of the escape time from a metastable state in the presence of colored noise, generated by Ornstein-Uhlenbeck process. We analyze the role of the correlated noise…
Noise Induced Phenomena in Lotka-Volterra Systems
B. Spagnolo, A. Fiasconaro, D. Valenti
We study the time evolution of two ecosystems in the presence of external noise and climatic periodical forcing by a generalized Lotka-Volterra (LV) model. In the first ecosystem,…
