Inhibiting Three-Body Recombination in Atomic Bose-Einstein Condensates
Chris P. Search, Weiping Zhang, Pierre Meystre
We discuss the possibility of inhibiting three-body recombination in atomic Bose-Einstein condensates via the application of resonant laser pulses. These pulses result in the…
A fundamental limit for integrated atom optics with Bose-Einstein condensates
Weiping Zhang, Ewan M. Wright, Han Pu +1
The dynamical response of an atomic Bose-Einstein condensate manipulated by an integrated atom optics device such as a microtrap or a microfabricated waveguide is studied. We show…
Two-fermion bound state in a Bose-Einstein condensate
Weiping Zhang, Han Pu, Chris P. Search +2
A nonlinear Schrödinger equation is derived for the dynamics of a beam of ultracold fermionic atoms traversing a Bose-Einstein condensate. The condensate phonon modes are shown to…
Fragmented Condensate Ground State of Trapped Weakly Interacting Bosons in Two Dimensions
Xia-Ji Liu, Hui Hu, Lee Chang +3
The ground state and its structure for a rotating, harmonically trapped N-Boson system with a weak repulsive contact interaction are studied as the angular momentum L increases up…
Optical detection of a BCS phase transition in a trapped gas of fermionic atoms
Weiping Zhang, C. A. Sackett, R. G. Hulet
Light scattering from a spin-polarized degenerate Fermi gas of trapped ultracold Li-6 atoms is studied. We find that the scattered light contains information which directly reflect…
Photonic band gaps and defect states induced by excitations of Bose-Einstein condensates in optical lattices
Karl-Peter Marzlin, Weiping Zhang
We study the interaction of a Bose-Einstein condensate, which is confined in an optical lattice, with a largely detuned light field propagating through the condensate. If the conde…
Acceleration of quasi-particle modes in Bose-Einstein condensates
Karl-Peter Marzlin, Weiping Zhang
We analytically examine the dynamics of quasi-particle modes occuring in a Bose-Einstein condensate which is subject to a weak acceleration. It is shown that the momentum of a quas…
Quantized circular motion of a trapped Bose-Einstein condensate: coherent rotation and vortices
Karl-Peter Marzlin, Weiping Zhang
We study the creation of vortex states in a trapped Bose-Einstein condensate by a rotating force. For a harmonic trapping potential the rotating force induces only a circular motio…
Vortex coupler for atomic Bose-Einstein condensates
Karl-Peter Marzlin, Weiping Zhang, Ewan M. Wright
A coherent coupler is proposed to spin a Bose-Einstein condensate composed of ultracold alkali atoms into a vortex state (VS). The proposal is based on a Raman transition induced b…
Laser-induced Rotation of a Trapped Bose-Einstein Condensate
Karl-Peter Marzlin, Weiping Zhang
In this letter, atom optic techniques are proposed to control the excitation of a Bose-Einstein condensate in an atomic trap. We show that by employing the dipole potential induced…
