Saturating interaction in coherently coupled two-component Bose-Einstein condensates
R Eid, S Tiengo, M Lévy +1
Rabi-coupled spinor Bose-Einstein condensates, with competing intra-and interspecies interactions, enable independent control of two-and three-body interactions. We show that coupl…
Three-body interactions in Rabi-coupled Bose gases: a perturbative approach
S Tiengo, R Eid, T Bourdel
In ultracold atomic gases, radio-frequency coupling between two spin states can lead to atoms being in a stable coherent superposition of the two states (dressed states). When the…
A simple magnetic field stabilization technique for atomic Bose-Einstein condensate experiments
S Tiengo, R Eid, M Apfel +2
We demonstrate a simple magnetic field stabilization technique in a Bose-Einstein condensate experiment. Our technique is based on the precise measurement of the current fluctuatio…
Ultra-cold atoms quantum tunneling through single and double optical barriers
Roy Eid, Alfred Hammond, Lucas Lavoine +1
We realize textbook experiments on Bose-Einstein condensate tunnelling through thin repulsive potential barriers. In particular, we demonstrate atom tunnelling though a single opti…
