Non-equilibrium Thermodynamics of Phase Separation in Binary Mixtures of Particles at Different Temperatures
Poster 206The phase behavior of the systems that remain non-equilibrium even in their stationary state is still a challenging open question in non-equilibrium statistical physics since the underlying physical principles are not well established yet. The near-equilibrium principles do not apply in their traditional form since the free energy concept does not apply to determine the system’s final state due to the lack of a well-defined temperature.
It is already well established in the field that the mixture of particles coupled to heat baths with different temperatures with purely repulsive interactions will undergo phase separation.
In this study, we propose a theoretical framework complemented by Langevin dynamics simulations to elucidate the phase behavior of particles coupled to heat baths at different temperatures. Specifically, we quantify the phase separation of this mixture by extremal properties of the free entropy functional.
