Coexistence of distinct nonuniform nonequilibrium steady states in Ehrenfest multiurn model on a ring
Chi-Ho Cheng, Pik-Yin Lai
The recently proposed Ehrenfest M-urn model with interactions on a ring is considered as a paradigm model which can exhibit a variety of distinct nonequilibrium steady states. Unli…
Non-equilibrium Dynamics and Phase Transitions in Potts model and Interacting Ehrenfest urn model
Chi-Ho Cheng, Pik-Yin Lai
We show that the recently proposed interacting Ehrenfest M-urn model at equilibrium can be exactly mapped to a mean-field M-state Potts model. By exploiting this correspondence, we…
Theory of Non-equilibrium Asymptotic State Thermodynamics: Interacting Ehrenfest Urn Ring as an Example
Chi-Ho Cheng, Pik-Yin Lai
A generalized class of non-equilibrium state, called non-equilibrium asymptotic state (NEAS), is proposed. The NEAS is constructed within the framework of the Fokker-Planck equatio…
Analytical Studies of the Magnetic Domain Wall Structure in the presence of Non-uniform Exchange Bias
Yee-Mou Kao, Chi-Ho Cheng
The pinning phenomena of the domain wall in the presence of exchange bias is studied analytically. The analytic solution of the domain wall spin configuration is presented. Unlike…
Non-equilibrium thermodynamics and Phase transition of Ehrenfest urns with interactions
Chi-Ho Cheng, Pik-Yin Lai
Ehrenfest urns with interaction that are connected in a ring is considered as a paradigm model for non-equilibrium thermodynamics and is shown to exhibit two distinct non-equilibri…
Phase Transitions in Ehrenfest Urns Model with Interactions: Coexistence of uniform and non-uniform states
Chi-Ho Cheng, Beverly Gemao, Pik-Yin Lai
A model based on the classic non-interacting Ehrenfest urn model with two-urns is generalized to urns with the introduction of interactions for particles within the same urn. A…
