Optical pumping of an atomic sample with narrow-band light can create sub-Doppler features, known as Bennett structures, in the velocity distribution of state populations. In the presence of static magnetic or electric fields, the corresponding sub-Doppler features in the index of refraction can cause nonlinear optical rotation and induced ellipticity of resonant light propagating through the a...

We present our the construction of an atom interferometer for inertial sensing in microgravity, as part of the I.C.E. (Interférométrie Cohérente pour l’Espace) collaboration. On-board laser systems have been developed based on fibre-optic components, which are insensitive to mechanical vibrations and acoustic noise, have sub-MHz linewidth, and remain frequency stabilised for weeks at a time. A ...

We evaluate the effective number of atoms in experiments where a probe laser beam with a Gaussian transverse profile passes through an atomic medium consisting in a cold atom cloud released from a magnetooptical trap. Considering the case where the initial distribution is a Gaussian function of position and of velocity, we give a quantitative description of the temporal variation of the effecti...

The spin-polarization at the V~001! surface has been studied by using different local @local spin-density approximation ~LSDA!# and semilocal @generalized gradient approximation ~GGA#! approximations to the exchange-correlation potential of DFT within two ab initio methods: the all-electron tight-binding linear muffin-tin orbital atomic-sphere approximation and the pseudopotential linear combin...
