Generation of spatiotemporal colored noise
García Ojalvo, Jordi; Ramírez de la Piscina Millán, Laureano; Sancho, Jose Maria (American Physical Society, 1992-10-01)
Article
Accés obertWe develop an algorithm to simulate a Gaussian stochastic process that is non-δ-correlated in both space and time coordinates. The colored noise obeys a linear reaction-diffusion Langevin equation with Gaussian white noise. ... -
Growth of unstable interfaces in disordered media

Article
Accés obertThe effects of a disordered medium in the growth of unstable interfaces are studied by means of two local models with multiplicative and additive quenched disorder, respectively. For short times and large pushing ... -

Higher order colored noise effects in multivariable systems.
Ramírez de la Piscina Millán, Laureano; Sancho, Jose Maria (American Physical Society, 1988-06-01)
Article
Accés obertWe extend the partial resummation technique of Fokker-Planck terms for multivariable stochastic differential equations with colored noise. As an example, a model system of a Brownian particle with colored noise is studied. ... -

Langevin equations with multiplicative noise: application to domain growth
Sancho, Jose Maria; Hernández-Machado, A.; Ramírez de la Piscina Millán, Laureano; Lacasta Palacio, Ana María (Jagiellonian University, Polish Academy of Arts and Sciences, 1993-05-01)
Article
Accés obertLangevin Equations of Ginzburg--Landau form, with multiplicative noise, are proposed to study the effects of fluctuations in domain growth. These equations are derived from a coarse-grained methodology. The Cahn--Hiliard--Cook ... -
