Achieving steady-state Bose-Einstein condensation

Juana S. Williams, R. Walser, Carl Wieman +2 more

We investigate the possibility of obtaining Bose-Einstein condensation (BEC) in a steady state by continuously loading atoms into a magnetic trap while keeping the frequency of the radio frequency field fixed. A steady state is obtained when the gain of atoms due to loading is balanced with the three dominant loss mechanisms due to elastic collisions with hot atoms from the background gas, inelastic three-body collisions, and evaporation. We describe our model of this system and present results of calculations of the peak phase-space density ${\ensuremath{\rho}}_{0}$ in order to investigate the conditions under which one can reach the regime ${\ensuremath{\rho}}_{0}>~2.612$ and attain BEC in steady state.

Stationary States of a Rotating Bose-Einstein Condensate: Routes to Vortex Nucleation

Kirk W. Madison, Frédéric Chevy, Vincent Bretin +1 more

Using a focused laser beam we stir a 87Rb Bose-Einstein condensate confined in a magnetic trap. We observe that the steady states of the condensate correspond to an elliptic cloud, stationary in the rotating frame. These steady states depend nonlinearly on the stirring parameters (amplitude and frequency), and various solutions can be reached experimentally depending on the path followed in this parameter space. These states can be dynamically unstable and we observe that such instabilities lead to vortex nucleation in the condensate.

Dynamics of Component Separation in a Binary Mixture of Bose-Einstein Condensates

David S. Hall, M. R. Matthews, J. R. Ensher +2 more

We present studies of the time-evolution of a twocomponent system of Bose-Einstein condensates (BEC) in the |F = 1, m f = -1 and |2, 1 spin states of 87 Rb.The two condensates are created with a well-defined relative phase and complete spatial overlap.In subsequent evolution they undergo complex relative motions that tend to preserve the total density profile.The motions quickly damp out, leaving the condensates in a steady state with a nonnegligible (and adjustable) overlap region.
