Abstract
We consider a single atom in an optical lattice, subject to a harmonic trapping potential. The problem is treated in the tight-binding approximation,
trap. It is shown that the kappa-->0 limit of this problem is singular,
is qualitatively different from that of a translationally invariant
densities of states and wave functions are exhibited and explained.
