Quantum signature of analog Hawking radiation in momentum space
D. Boiron, A. Fabbri, P. -É. Larré +3
We consider a sonic analog of a black hole realized in the one-dimensional flow of a Bose-Einstein condensate. Our theoretical analysis demonstrates that one- and two-body momentum…
Bose-Einstein Condensation and Spin Mixtures of Optically Trapped Metastable Helium
G. B. Partridge, J. -C. Jaskula, M. Bonneau +2
We report the realization of a BEC of metastable helium-4 atoms (4He*) in an all optical potential. Up to 10^5 spin polarized 4He* atoms are condensed in an optical dipole trap for…
Atomic density of an harmonically trapped ideal gas near Bose-Einstein transition temperature
Rodolphe Hoppeler, Jose Viana Gomes, Denis Boiron
We have studied the atomic density of a cloud confined in an isotropic harmonic trap at the vicinity of the Bose-Einstein transition temperature. We show that, for a non-interactin…
Using ion production to monitor the birth and death of a metastable helium Bose-Einstein condensate
S. Seidelin, O. Sirjean, J. Viana Gomes +3
We discuss observations of the ion flux from a cloud of trapped metastable helium atoms. Both Bose-Einstein condensates and thermal clouds were investigated. The ion flux is compar…
Ionization rates in a Bose-Einstein condensate of metastable Helium
O. Sirjean, S. Seidelin, J. Viana Gomes +4
We have studied ionizing collisions in a BEC of He*. Measurements of the ion production rate combined with measurements of the density and number of atoms for the same sample allow…
Thermalization of magnetically trapped metastable helium
A. Browaeys, A. Robert, O. Sirjean +5
We have observed thermalization by elastic collisions of magnetically trapped metastable helium atoms. Our method directly samples the reconstruction of a thermal energy distributi…
