Coarse-graining is a frequently-used procedure to bridge molecular modeling with experiments. In equilibrium systems, this task can be readily performed; however in systems outside equilibrium, a possible lack of equilibration of the eliminated degrees of freedom may lead to incomplete or even misleading descriptions. Here, we present some examples showing how an improper coarse-graining procedure may result in linear approaches to nonlinear processes, miscalculations of activation rates and violations of the fluctuation-dissipation theorem.11 p.application/pdfengcc-by-nc (c) Rubí Capaceti, José Miguel et al., 2013http://creativecommons.org/licenses/by-nc/3.0/esTermodinàmica del desequilibriFísica estadísticaProcessos estocàsticsMecànica estadística del no equilibriNonequilibrium thermodynamicsStatistical physicsStochastic processesNonequilibrium statistical mechanicsinfo:eu-repo/semantics/article6271232014-03-20info:eu-repo/semantics/openAccess
