I have investigated the quantum mechanics of liquid helium, calculating properties of the bulk fluid as well as the surface (density profile and surface excitations).
I am interested in applying statistical mechanics to the analysis of simple models of real-world systems. An analysis of a simple model of displacive ferroelectrics led to an interesting phase diagram and an understanding of mode softening as the precursor of a displacive transition. With a biologically-oriented coworker, I have studied the equilibrium between a membrane (wilh sites which can adsorb molecules) and a fluid containing those molecules. We have studied fairly complicated membranes, taking account of the geometrical competition for sites and also including electrostalic effecls in a mean-field approximation.
In September 2011 I completed an elementary text, or supplementary text, on Classical Mechanics. The book incorporates my ideas on how to present the basic concepts, and is available (free) online. (See link above).
