Abstract
We study the existence and properties of the non-equilibrium steady state which arises by putting two copies of systems at different temperatures into a thermal contact. We solve the problem for the relativistic systems that are described by the energy-momentum of a perfect hydro with general equation of state (EOS). In particular, we examine several simple examples: a hydro with a linear EOS, a holographic CFT perturbed by a relevant operator and a barotropic fluid, i.e., \( P=P\left(\mathrm{\mathcal{E}}\right) \). Our studies suggest that the formation of steady state is a universal result of the hydro regime regardless of the kind of fluid.
