Abstract : We present a linear state equation between kinetic temperature and mass density that has been widely verified in boundary-driven one-dimensional nonequilibrium systems. We show that this relation holds even more universally and in particular when standard relations between purely mechanical and thermodynamic quantities do not apply. We investigate special situations in which phase transitions occur and the relation fails, as common in statistical mechanics. We also provide a theoretical explanation of how this happens.

Abstract : Totally Asymmetric Simple Exclusion Process is a stochastic model to recognize the nature of non-equilibrium transport systems. Inspired by the vehicular traffic phenomena, we have actuated a new kind of coupling rule on transport dynamics. The impact of the designed dynamics on system properties has been analyzed over phase diagrams, phase transitions, finite size effect, and shock position. The calculated numerical results from mean-field theory are verified through the ground of Monte Carlo simulation.

Abstract : Many systems in nature seem to be poised at criticality. Self-organized criticality $(SOC)$ suggests a mechanism by which the dynamics of the system intrinsically evolve into a critical state without any parameter tuning. We will describe the concept of SOC and present a new route obtained through temporal fluctuations in stochastic networks with applications to epidemic models over dynamic scale-free graphs, offering a possible explanation for why some epidemics, which we expect to disappear, don't.

Abstract : A one-dimensional linear autonomous system coupled to a generic stationary nonequilibrium fluctuating bath can exhibit a resonant response when its damped oscillation period matches some characteristic bath’s relaxation time. This condition justifies invoking the stochastic resonance paradigm, even if it can be achieved more easily by tuning the system to the bath and not vice versa, as is usually the case. The simple nature of the mechanism numerically investigated here suggests number of exciting applications

Abstract : The recently developed Hessian geometry of force and flux spaces in chemical reaction networks provides a geometric derivation of TUR. The relations are obtained from a comparison of two Riemannian metric tensors - one characterizes the pseudo entropy production and the other the current fluctuations. This geometry yields a characterization of the error term as the norm of a linear subspace component of the flux vector and thus characterizes the fluxes where TUR become equalities.
