Proceedings of the Sixteenth International Workshop held in San Juan, Puerto Rico in June 1992. Papers are divided into a broad range of topics: solid state physics, superconductivity, quantum fluids, nuclear physics, atoms and molecules, classical fluids, polymers, plasmas, lattice theories, phase transitions, cellular automata, and fundamental quantum mechanics. Participants discussed density function theory, dynamics of metal films, coulomb coupling, nucleonic superfluids, time-dependent n-level systems, fluids of hard convex molecules, and line tension at wetting and pre-wetting transitions.
