Density functional theory and field theoretic methods in both classical and quantal systems; matter at high densities and in reduced dimensionality, including the two-dimensional electron gas and confined electron systems; superlattice hetero-structures, their electronic structure, and their transport properties; metallic hydrogen and its electronically ordered alloys. The general theory of superconductivity.
Present research themes are centered on the theory of strongly correlated many-particle systems, both classical and quantal, and high-temperature superconductivity.
Topics of special interest include:
- Chemical pre-compression, and higher superconductivity in the lower elements in combination
- Ground state liquid metals and their possible superfluidity
- Ordered states of condensed matter at elevated pressures
- Quantum and classical density functional theories (and applications)
- General symmetry aspects of the metal-insulator transition
- Theory of melting, and other first-order phase transitions
- Theory of metallic hydrogen and its alloys
