Ergodic properties of the harmonic process
Frank Redig, Berend van Tol
In this paper we study detailed fluctuation results for a class of non-equilibrium steady states. The main example is the boundary driven harmonic model \cite{frassek2022exact}. In…

Non-equilibrium steady states with a spatial Markov structure
Frank Redig, Berend van Tol
We investigate the structure of non-equilibrium steady states (NESS) for a class of exactly solvable models in the setting of a chain with left and right reservoirs. Inspired by re…
