Test of the fluctuation theorem for stochastic entropy production in a nonequilibrium steady state Gómez Marín, Alejandro Pagonabarraga Mora, Ignacio Física Sistemes no lineals Physics Nonlinear systems We derive a simple closed analytical expression for the total entropy production along a single stochastic trajectory of a Brownian particle diffusing on a periodic potential under an external constant force. By numerical simulations we compute the probability distribution functions of the entropy and satisfactorily test many of the predictions based on Seiferts integral fluctuation theorem. The results presented for this simple model clearly illustrate the practical features and implications derived from such a result of nonequilibrium statistical mechanics. 2011-07-07T12:54:13Z 2011-07-07T12:54:13Z 2006 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion 1063-651X https://hdl.handle.net/2445/18861 553304 eng Reproducció del document publicat a: http://dx.doi.org/10.1103/PhysRevE.74.061113 Physical Review E, 2006, vol. 74, núm. ,p. 061113-1-061113-8 http://dx.doi.org/10.1103/PhysRevE.74.061113 (c) American Physical Society, 2006 info:eu-repo/semantics/openAccess 8 p. application/pdf The American Physical Society Articles publicats en revistes (Física de la Matèria Condensada)
