Session KP01 - Poster Session III.
POSTER session, Tuesday afternoon, March 23
Exhibit Hall, GWCC
Excitation and decay of Bose-Einstein condensates in a 3D trap are studied by direct solution of the time-dependent nonlinear Schrodinger equation. The Hamiltonian is discretized on a 3D lattice using finite differences. The condensate wavefunction is partitioned on a distributed-memory parallel computer and then time evolved using an explicit leap-frog propagator. The nonlinear response of ground state alkali metal condensates in a fully anisotropic trap is studied using both single and broadband frequency probes. Comparison is made with previous theoretical results and experimental measurements of the excitation frequencies.
