Abstract
The effects of quantum statistics and atomic correlations on motion in two-dimensional periodic potentials is studied within a Hubbard model for both Bose–Einstein and Fermi–Dirac statistics. Exact eigenstates are obtained for finite clusters with periodic boundary conditions, and the extent of ground state delocalization evaluated for both statistics.Keywords
