Thermodynamic Perturbation Theory for Classical Systems Based on Self-Consistent Field Model

Section: General problems of theoretical physics
Language: English

Abstract: A formulation of the thermodynamic perturbation theory for classical many-particle systems, which is based on a self-consistent field model as the main approximation, has been proposed. Systems of particles in a spatially homogeneous state and in external fields that increase or decrease as the distance from the surface changes are considered as an example. The application of the self-consistent field approach as the main approximation is found to enable the description of many-particle systems, in which the concentration of particles and the interactions between them are not low, as well as phase transitions in such systems.

Key words: perturbation theory, self-consistent field, thermodynamic quantities, dense gases and fluids.
