Abstract : This document is the final report for AFOSR grant F4962O-95-1-O285, "The Dynamics of Correlations in Lattice Gases." Under the terms of this grant, the Center for Computational Science at Boston University provided theoretical and computational support to the Lattice-Gas Theory and Computation group at the Geophysics Directorate of Phillips Laboratory (AFOSR task 2304CP). Twelve publications have resulted from this effort, as well as the sponsorship of the Sixth International Conference on Discrete Models for Fluid Mechanics and the preparation of the proceedings of that meeting as a special issue of the International Journal of Modern Physics C. In addition to applying lattice-gas algorithms to systems of complex fluids and droplets, the work has resulted in two significant extensions of the lattice-gas algorithm: These are integer lattice gases which are proving to be an important methodology for the matching of microscopic, particulate, kinetic descriptions to macroscopic, continuum hydrodynamics, and quantum lattice gases which provide a paradigm for the simulation of physical systems on quantum computers. Moreover, we have shown that lattice-gas algorithms can be among the most efficient methods of simulating certain systems of interest in materials science, such as immiscible and amphiphilic fluids.
