Collapse of Bose-Einstein condensates with dipole-dipole interactions

Bose-Einstein condensation of dilute trapped atomic gases @1,2# essentially depends on the interparticle interactions. In most experiments so far the dominated interactions have been short-range van der Waals forces which are characterized by the s-wave scattering length a. Spatially homogeneous condensates with positive scattering length ~repulsive interaction! are stable while condensates wit...

Effective dipole-dipole interactions in multilayered dipolar Bose-Einstein condensates

We propose a two-dimensional model for a multilayer stack of dipolar Bose-Einstein condensates formed by a strong optical lattice. We derive effective intraand interlayer dipole-dipole interaction potentials and provide simple analytical approximations for a given number of lattice sites at arbitrary polarization. We find that the interlayer dipole-dipole interaction changes the transverse aspe...

Bose-Einstein Condensation in a CO2-laser Optical Dipole Trap

We report on the achieving of Bose-Einstein condensation of a dilute atomic gas based on trapping atoms in tightly confining CO2-laser dipole potentials. Quantum degeneracy of rubidium atoms is reached by direct evaporative cooling in both crossed and single beam trapping geometries. At the heart of these alloptical condensation experiments is the ability to obtain high initial atomic densities...

Stabilities of one-dimensional stationary states of Bose-Einstein condensates

We explore the dynamical stabilities of a quasi-one dimensional (1D) Bose-Einstein condensate (BEC) consisting of fixed N atoms with time-independent external potential. For the stationary states with zero flow density the general solution of the perturbed time evolution equation is constructed, and the stability criterions concerning the initial conditions and system parameters are established...
