Critical Phenomena and Diffusion in Complex Systems
Bernardo Spagnolo, Alexander A. Dubkov
Editorial of the International Conference on Critical Phenomena and Diffusion in Complex Systems held on 5--7 December, 2006 in Nizhniy Novgorod State University, Russia and was de…
Langevin Approach to Levy Flights in Fixed Potentials: Exact Results for Stationary Probability Distributions
A. A. Dubkov, B. Spagnolo
The functional method to derive the fractional Fokker-Planck equation for probability distribution from the Langevin equation with Levy stable noise is proposed. For the Cauchy sta…
Extinction statistics in N random interacting species
Alessandro Fiasconaro, Bernardo Spagnolo
A randomly interacting N-species Lotka-Volterra system in the presence of a Gaussian multiplicative noise is analyzed. The investigation is focused on the role of this external noi…
Lifetime of metastable states and suppression of noise in Interdisciplinary Physical Models
B. Spagnolo, A. A. Dubkov, A. L. Pankratov +3
Transient properties of different physical systems with metastable states perturbed by external white noise have been investigated. Two noise-induced phenomena, namely the noise en…
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…
