Estimating entropy rate from censored symbolic time series: a test for time-irreversibility
Raul Salgado-Garcia, Cesar Maldonado
In this work we introduce a method for estimating entropy rate and entropy production rate from finite symbolic time series. From the point of view of statistics, estimating entrop…
Open Markov chains: cumulant dynamics, fluctuations and correlations
R. Salgado-Garcia
In this paper we propose a model for open Markov chains that can be interpreted as a system of non-interacting particles evolving according to the rules of a Markov chain. The numb…
Noise-induced rectification in out-of-equilibrium structures
R. Salgado-Garcia
We consider the motion of overdamped particles on random potentials subjected to a Gaussian white noise and a time-dependent periodic external forcing. The random potential is mode…
Unbiased diffusion of Brownian particles on disordered correlated potentials
Raul Salgado-Garcia, Cesar Maldonado
In this work we study the diffusion of non-interacting overdamped particles, moving on unbiased disordered correlated potentials, subjected to Gaussian white noise. We obtain an ex…
