What is Approach to Equilibrium and Nonequilibrium Stationary Distributions of Interacting Many-particle Systems That Are Coupled to Different Heat Baths about?
A Hamiltonian-based model of many harmonically interacting massive particles that are subject to linear friction and coupled to heat baths at different temperatures is used to study the dynamic approach to equilibrium and nonequilibrium stationary states. An equilibrium system is here defined as a system whose stationary distribution equals the Boltzmann distribution, the relation of this definition to the conditions of detailed balance and vanishing probability current is discussed both for underdamped as well as for overdamped systems. Based on the exactly calculated dynamic approach to the stationary distribution, the functional that governs this approach, which is called the free entropy S\_{free}(t), is constructed. For the stationary distribution S\_{free}(t) becomes maximal and its time derivative, the free entropy production S[over ̇]\_{free}(t), is minimal and vanishes. Thus, S\_{free}(t) characterizes equilibrium as well as nonequilibrium stationary distributions by their extremal and stability properties. For an equilibrium system, i.e., if all heat baths have the same temperature, the free entropy equals the negative free energy divided by temperature and thus correspon
