Two-component Bose-Einstein Condensates
This talk is about two-component Bose-Einstein condensate in a harmonic trap. The aim is to describe the shape and the spatial configuration of the ground state pairs. We will show links between our model and other mathematical problems : optimal partition problems and the Cahn-Hilliard model for phase transition. These links appear in our model in the limit when intercomponent particle interac...
متن کاملSpinor Bose-Einstein condensates in optical traps
We have studied the equilibrium state of spinor condensates in an optical trap [1]. In contrast to magnetically trapped condensates, spinor condensates have the orientation of the spin as a degree of freedom, which can be described by a multi-component wavefunction (one for each magnetic sublevel). In an F=1 spinor condensate subject to spin relaxation, two mF=0 atoms can collide and produce a ...
متن کاملBose-Einstein Condensates in Magnetic Micro Traps
In a recent experiment we have demonstrated the generation of a Rubidium condensate inside a magnetic micro trap. The lifetime and the heating rate of the atomic cloud at di®erent distances from the trap surface has been determined. A surface induced potential structure of unknown origin has been identi ̄ed by observing a periodic fragmentation of the atomic cloud. 1 Magnetic Micro Potentials Pr...
متن کاملBose-Einstein condensates in strongly disordered traps.
A Bose-Einstein condensate in an external potential consisting of a superposition of a harmonic and a random potential is considered theoretically. From a semiquantitative analysis we find the size, shape, and excitation energy as a function of the disorder strength. For positive scattering length and sufficiently strong disorder the condensate decays into fragments each of the size of the Lark...
متن کاملTwo-mode entanglement in two-component Bose-Einstein condensates
Abstract We study the generation of two-mode entanglement in a two-component Bose-Einstein condensate trapped in a double-well potential. By applying the Holstein-Primakoff transformation, we show that the problem is exactly solvable as long as the number of excitations due to atom-atom interactions remains low. In particular, the condensate constitutes a symmetric Gaussian system, thereby enab...
