We measure atom number statistics after splitting a gas of ultracold Rb 87 atoms in a purely
magnetic double-well potential created on an atom chip. Well below the critical temperature …

We consider quantum statistical physics of many-body equilibrium fluctuations in an
interacting Bose-Einstein-condensed (BEC) gas. We find a universal analytic formula for a …

We propose a multi-qubit Bose–Einstein-condensate (BEC) trap as a platform for studies of
quantum statistical phenomena in many-body interacting systems. In particular, it could …

We calculate the Bose-Einstein-condensate (BEC) occupation statistics vs the interparticle
interaction in a dilute gas with a nonuniform condensate in a box trap within the Bogoliubov …

A double well loaded with bosonic atoms represents an ideal candidate to simulate some of
the most interesting aspects in the phenomenology of thermalisation and equilibration. Here …

We study the tunneling dynamics and energy bands of three Bose-Einstein condensates
which are coupled weakly with each other. The study is carried out with both the mean-filed …

We propose a method to measure the normal fraction of a two-dimensional Bose gas, a
quantity that generally differs from the noncondensed fraction. The idea is based on …

Based on counting statistics and Bogoliubov theory, we present a recurrence relation for the
microcanonical partition function for a weakly interacting Bose gas with a finite number of …

We describe boson sampling of interacting atoms from the noncondensed fraction of Bose–
Einstein-condensed (BEC) gas confined in a box trap as a new platform for studying …

Dans ce mémoire, nous décrivons le montage d'une expérience permettant la production de
condensats de Bose-Einstein d'atomes de 87Rb sur une puce à atomes, ainsi que leur …
