On the Thomas-fermi Approximation for Bose Condensates in Traps
Thomas-Fermi theory for Bose condesates in inhomogeneous traps is revisited. The phase-space distribution function in the Thomas-Fermi limit is f0(R,p) α δ(μ −Hcl) where Hcl is the classical counterpart of the self-consistent GrossPitaevskii Hamiltonian. No assumption on the large N-limit is introduced and, e.g the kinetic energy is found to be in good agreement with the quantal results even fo...
متن کاملSelf-Gravitating Bose-Einstein Condensates and the Thomas-Fermi Approximation
Abstract: Self-gravitating Bose-Einstein condensates (BEC) have been proposed in various astrophysical contexts, including Bose-stars and BEC dark matter halos. These systems are described by a combination of the Gross-Pitaevskii and Poisson equations (the GPP system). In the analysis of these hypothetical objects, the Thomas-Fermi (TF) approximation is widely used. This approximation is based ...
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...
