In fig. 3a) we see 8 bright states, 2 weakly coupled states and 8 dark states combining both hyperfine manifolds. 3b) we plot the optical pumping rates of the corre- sponding

Several identified reasons have been examined : (i) heating of the atomic cloud due to the technical noise coming from the rf source used to dress the atoms and, (ii) heating

One point is going back 7 mm away from A to the position O of the initial quadrupole centre whereas the other one is going from A to infinity in the opposite direction (see Ref.

These comprise a new part of the vacuum assembly, including the transport region and the ultra-high vacuum chamber, with a pressure lower than 10 −11 mbar in the science cell, the

Here we present a systematic study of the spin trans- port in an elongated harmonic trap based on the Boltz- mann equation using a combination of analytical and nu- merical methods
