Colored noise in spatially extended systems García Ojalvo, Jordi Sancho, José M. Física matemàtica Física estadística Termodinàmica Sistemes dinàmics diferenciables Mathematical physics Statistical physics Thermodynamics Differentiable dynamical systems We study the effects of time and space correlations of an external additive colored noise on the steady-state behavior of a time-dependent Ginzburg-Landau model. Simulations show the existence of nonequilibrium phase transitions controlled by both the correlation time and length of the noise. A Fokker-Planck equation and the steady probability density of the process are obtained by means of a theoretical approximation. 2011-07-07T12:52:04Z 2011-07-07T12:52:04Z 1994 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion 1063-651X https://hdl.handle.net/2445/18758 60153 eng Reproducció document publicat a: http://dx.doi.org/10.1103/PhysRevE.49.2769 Physical Review E, 1994, vol. 49, núm. 4, p. 2769-2778 http://dx.doi.org/10.1103/PhysRevE.49.2769 (c) The American Physical Society, 1994 info:eu-repo/semantics/openAccess 10 p. application/pdf application/pdf The American Physical Society Articles publicats en revistes (Física Quàntica i Astrofísica)
