We describe a powerful method for determining the equation of state of an ultracold gas from
in situ images. The method provides a measurement of the local pressure of a harmonically …

We report on the experimental observation of vortex formation and production of tangled
vortex distribution in an atomic BEC of 87 Rb atoms submitted to an external oscillatory …

We analyze the behavior of the anomalous density as function of the radial distance at
different temperatures in a variational framework. We show that the temperature …

We study the properties of Bose–Einstein condensate–impurity mixtures at finite
temperatures employing the Balian–Vénéroni variational principle. The method leads to a …

We apply the time-dependent variational principle of Balian-Vénéroni to a system of self-
interacting trapped bosons at finite temperature. The method leads to a set of coupled non …

Ultracold Bose gases at nonzero temperatures have recently proven to be a rich field of
investigation, especially that all experiments actually take place at nonzero temperatures …

Введение. Бозе-эйнштейновские конденсаты (БЭК) разреженных газов [1, 2] являются
сейчас наиболее точной реализацией предсказанной Эйнштейном конденсации …

Abstract Free expansion of Bose–Einstein condensates of rubidium atoms at finite
temperatures has been analyzed experimentally and theoretically. It has been shown that …

This article presents a firm mathematical foundation for the boundary value problem
associated with the nonrelativistic Thomas–Fermi equation for heavy atoms in intense …

We analyse numerically the finite-temperature behaviour of a dilute trapped Bose gas
containing a large number of atoms. The generalized Hartree–Fock–Bogoliubov …
