Study of Thermodynamically Inspired Quantities for Both Thermaland External Colored Non-Gaussian Noises Driven Dynamical System

[摘要] We have studied dynamics of both internal and external noises-driven dynamicalsystem in terms of information entropy at both nonstationary and stationary states. Herea unified description of entropy flux and entropy production is considered. Based on theFokker-Planck description of stochastic processes and the entropy balance equation we havecalculated time dependence of the information entropy production and entropy flux in presenceand absence of nonequilibrium constraint (NEC). In the presence of NEC we have observedextremum behavior in the variation of entropy production as function of damping strength, noisecorrelation, and non-Gaussian parameter (which determine the deviation of external noise behaviorfrom Gaussian characteristic), respectively. Thus the properties of noise process are important forentropy production.
