This chapter is an introduction to the thermodynamics of systems, based on the correlation function formalism, which has been established to determine the thermodynamic properties of simple liquids. The article begins with a preamble describing few general aspects of the liquid state, among others the connection between the phase diagram and the pair potential u(r), on one hand, and between the...

A simple perturbation theory of the frequencies and density distortions of the I= 1 diocotron mode on pure electron plasma columns is presented. This mode is the dynamical state of an off-axis electron column which is orbiting around the containment axis at the ExB drift velocity. The theory predicts shifts in the orbit frequency and quadrupole distortions of the plasma surface, both varying as...
