It is a remarkable fact that matter can exist in so many different phases under the appropriate circumstances. In addition to the usual gas, liquid and solid phases, there are ferromagnets , antiferromagnets , ferroelectrics, superfluids, superconductors, gels, Bose-Einstein condensation in fermionic systems and ulndoubtedly many more that we have yet to discover.

Scientists at Lehigh currently study both equilibrium and nonequilibrium aspects of phase transitions, such as the phase diagrams and crystal nucleation rates of globular proteins in solution, heterogeneous nucleation , dislocation theory and Rayleigh-Benard convection. A variety of theoretical and computational methods are employed in these studies, including density functional theory, renormalization group theory, Monte Carlo simulations and umbrella sampling techniques.
