It is shown that in a constant external potential the kinetic variational theory II (KVT II) yields the correct single-particle equilibrium distribution function for a system interacting through a hard core plus a sufficiently short-ranged attractive tail.

A study is performed on the time correlation function for the equilibrium fluctuations of the longitudinal velocity in a compressible, heat insulating fluid, within the context of extended irreversible thermodynamics. The memory function is explicitly computed and shown to obey a double...

A variational method is used to get the eigenvalues and eigenfunctions of the one-dimensional Smoluchowski equation for two types of symmetric bistable potential fields. The effects of barrier height and width on the rate of escape of particles over the barrier (first non-zero eigenvalue) are...

A generalization of extended irreversible thermodynamics is obtained by including the gradients of conserved and nonconserved variables in the space of thermodynamical states. The relaxation equations for these additional state variables are derived systematically from the basic postulates of...

Using the liquid state thermodynamic perturbation theory and the hard-sphere fluid as the reference system, the liquid–glass transition line of Lennard–Jones and hard-core Yukawa fluids is computed. The results are presented both in the reduced density vs. reduced temperature and in the...
