Steady-state and transient properties of reaction-diffusion systems

In this paper we discuss different quantities that allow a characterization of steady-state and transient properties of nonequilibrium reaction-diffusion systems for which microscopic reversibility is broken. Using numerical exact techniques and numerical simulations we show that stationary probability currents allow to quantify the distance to equilibrium. When a system is forced out of a steady state, fluctuation ratios provide non-trivial insights into the microscopic dynamics of that system.
