Nuclear spin squeezing by continuous quantum non-demolition measurement: a theoretical study
Alan Serafin, Yvan Castin, Matteo Fadel +2
We propose to take advantage of the weak coupling of ground-state helium-3 nuclear spin to its environment to produce long-lived macroscopic quantum states, nuclear spin squeezed s…
Metastability Exchange Optical Pumping of Helium-3 at High Pressures and 1.5 T: Comparison of two Optical Pumping Transitions
Marie Abboud, Alice Sinatra, Geneviève Tastevin +2
At low magnetic field, metastability exchange optical pumping of helium-3 is known to provide high nuclear polarizations for pressures around 1 mbar. In a recent paper, we demonstr…
High nuclear polarization of helium-3 at low and high pressure by metastability exchange optical pumping at 1.5 Tesla
Marie Abboud, Alice Sinatra, Xavier Maitre +2
We perform metastability exchange optical pumping of helium-3 in a strong magnetic field of 1.5 T. The achieved nuclear polarization, from 80% at 1.33 mbar to 25% at 67 mbar, shows…
Penning collisions of laser-cooled metastable helium atoms
F. Pereira Dos Santos, F. Perales, J. Leonard +6
We present experimental results on the two-body loss rates in a magneto-optical trap of metastable helium atoms. Absolute rates are measured in a systematic way for several laser d…
Simultaneous Magneto-Optical Trapping of Two Lithium Isotopes
Marc-Oliver Mewes, Gabriele Ferrari, Florian Schreck +2
We confine 4 10^8 fermionic 6Li atoms simultaneously with 9 10^9 bosonic 7Li atoms in a magneto-optical trap based on an all-semiconductor laser system. We optimize the two-isotope…
Phase Dynamics of Bose-Einstein Condensates: Losses versus Revivals
Alice Sinatra, Yvan Castin
In the absence of losses the phase of a Bose-Einstein condensate undergoes collapses and revivals in time due to elastic atomic interactions. As experiments necessarily involve ine…
