Momentum-space engineering of gaseous Bose-Einstein condensates
Momentum-space engineering gaseous Bose-Einstein condensates
2010/10/21
We show how the momentum distribution of gaseous Bose–Einstein condensates can be shaped
by applying a sequence of standing–wave laser pulses. We present a theory of the effect of such a pulse sequen...
Non-Linear Dynamics of Continuously Measured Bose-Einstein Condensates in One-Dimensional Harmonic Traps
Non-Linear Dynamics Bose-Einstein Condensates One-Dimensional Harmonic Traps
2010/10/18
Continuous center-of-mass position measurements performed on an interacting harmonically
trapped Bose-gas are considered. Using both semi-analytical mean-field approach and completely
quantum numeri...

We demonstrate, through numerical simulations, the emission of a coherent continuous matter wave of constant amplitude from a Bose-Einstein Condensate in a shallow optical dipole trap. The process is ...
Solitons of two-component Bose-Einstein condensates modulated in space and time
Bose-Einstein condensates space and time
2010/4/1
In this paper we present soliton solutions of two coupled nonlinear Schodinger equations modulated in the bspace and time. The approach allows us to obatin solitons with large variety of solutions dep...
Decoherence in Bose-Einstein Condensates: towards Bigger and Better Schroedinger Cats
Decoherence Bose-Einstein Condensates Schroedinger Cats
2010/10/18
We consider a quantum superposition of Bose-Einstein condensates in two immiscible
internal states. A decoherence rate for the resulting Schr¨odinger cat is calculated and
shown to be a significant ...
