The PhET simulation was based on my molecular dynamics code used in the applet
above.

The following link is Java applet that simulates the two-dimensional Potts
model.

My general field of research is the thermodynamics and statistical mechanics of
condensed matter systems. This includes theoretical studies related to critical
phenomena and phase transitions, ferroelectrics, Landau theories, hysteresis in
spin models, magnetic materials, failure modes in random materials, theories of
melting, effects of noise on nonlinear dynamical systems, phenomenological
finite-size scaling, Monte Carlo methods, commensurate-incommensurate
transitions, renormalization-group methods, and structural phase transitions.

My recent work includes a calculation of the exact distribution of energies in
the two-dimensional Ising model. By using Kauffman's generalization of Onsager's
solution of the two-dimensional Ising model, one can calculate the exact form
of the partition function in the form of a low-temperature series expansion.
Since the coefficients of the low-temperature series give the number of
different states with a given energy, one can use the coefficients to calculate
the exact distribution of energies at any specified temperature. This solution
provides an exact distribution that can be used to verify the accuracy and
convergence of Monte Carlo simulations.
