Jiménez Aquino, José InésSancho, José M.2011-07-072011-07-0719931539-3755https://hdl.handle.net/2445/18723We present the relationship between nonlinear-relaxation-time (NLRT) and quasideterministic approaches to characterize the decay of an unstable state. The universal character of the NLRT is established. The theoretical results are applied to study the dynamical relaxation of the Landau model in one and n variables and also a laser model.5 p.application/pdfeng(c) The American Physical Society, 1993Física estadísticaTermodinàmicaSistemes dinàmics diferenciablesÒpticaStatistical physicsThermodynamicsDifferentiable dynamical systemsOpticsThe nonlinear relaxation time and quasideterministic-theory approaches to characterize the decay of unestable statesinfo:eu-repo/semantics/article84007info:eu-repo/semantics/openAccess
