Atom optics with rotating Bose-Einstein condensates

Atomic optics, Bose-Einstein condensates and atom lasers

In 1992, with the backing of CNRS, Alain Aspect founded the atomic optics group at the Institut d’Optique at Orsay, with Nathalie Westbrook and Robin Kaiser, and later Christoph Westbrook. Atomic optics is a new field of research which aims to use the forces exerted by lasers on atoms to control their paths, in the same way as traditional optics controls light rays with mirrors and lenses. From...

Rotating Matter Waves in Bose-Einstein Condensates

In this paper we consider analytically and numerically the dynamics of waves in twodimensional, magnetically trapped Bose-Einstein condensates in the weak interaction limit. In particular, we consider the existence and stability of azimuthally modulated structures such as rings, multi-poles, soliton necklaces, and vortex necklaces. We show how such structures can be constructed from the linear ...

Atom-atom correlations in colliding Bose-Einstein condensates

We analyze atom-atom correlations in the s-wave scattering halo of two colliding condensates. By developing a simple perturbative approach, we obtain explicit analytic results for the collinear CL and back-toback BB correlations corresponding to realistic density profiles of the colliding condensates with interactions. The results in the short-time limit are in agreement with the first-principl...
