Helium Liquids,ons which were phonon-like for small wave vector and of a more complex (roton) character at larger wave vectors, around the peak of the static structure factor .(.) as needed to account for superfluid properties. This description was made fairly precise by the work of Feynman (1954), which we shall first briefly summarize.

Static Structure and Thermodynamics,ce the structure of a crystal is determined experimentally by observing the Bragg reflections of X-rays, it is natural to seek a quantitative description of the liquid structure via the intensity . of X-rays scattered through an angle 2. say, from the liquid. If we introduce the usual variable . = 4

Liquid Dynamics and Time-Dependent Correlation Functions,n Hove 1954.). We argue purely classically at first. Suppose that we define .(.) as the average density of atoms at the point . at time ., if an atom was at the origin . = 0 at time . = O. Thus, .(.) gives us the correlation in the positions of two atoms, which may or may not be different, at differ

Structure and Dynamics of Binary Fluids,ralise, we shall present the treatment in terms of binary mixtures. The discussion, naturally enough, will start out with structure, at first static structure, but later we shall generalise this to dynamic properties.
