Statistical Mechanics of Simple Dense Fluids Using Functional Integration

Abstract

The use of functional integration in developing approximate equations of state for simple dense fluids is outlined. The repulsive (short range) and attraotive parts of the potential are treated separately and the grand partition function is expressed in terms of a functional integral which involves knowledge of the thermodynamio properties of the "short.range system". Two separate prooedures are outlined to obtain approximate equations of state for dense fluids from this exact functional integral.
