Abstract

We study a system of N trapped bosons in the Thomas-Fermi regime with an interacting pair potential of the form (gN) N3 beta-1V( N-beta x), for some beta is an element of(0, 1/3) and gN diverging as N ->infinity. We prove that there is complete Bose-Einstein condensation at the level of the ground state and, furthermore, that, if beta is an element of (0, 1/6), condensation is preserved by the time evolution.
