Production of Sodium Bose--Einstein condensates in an optical dimple trap

We are going to characterize a regime of fast rotation where there are no vortices in the bulk of the condensate and show that the coarse grained density profile is very different

Indeed, for reaching the 2R RF point, the atoms oscillating along the z axis need to overcome an extra (optical) potential energy given by ΔU = U dip (2R RF )... Figure 6.15:

We show that depending on the initial state of the atoms in the lattice, one faces a broadening and/or a shift of the atomic tran- sition of the order of the width of the lowest

Once the bead is confined in this quasi-harmonic potential, acquisitions are performed and the sinusoidal force applied on the bead in the bistable configuration applied on the bead

To conclude, we have presented a theoretical study of the dynamics of thermal and coherent ensemble of cold atoms in a simple optical beam splitter or deflector device. The effect

A contrario, si le succès ne survient pas dans ces disciplines qui mènent aux métiers de stars, lorsqu’on a une base, il n’est jamais trop tard pour reprendre ou continuer

Les deux types d’antiseptiques ont leur place dans notre monde, les antiseptiques de synthèse étaient toujours efficaces puisqu’ils sont plus commercialisés et

Our theoreti- cal calculations show that, by transferring the atoms into a shallow trap, the spin squeezed states created in [40] can survive more than 0.5 second under the influence
