We present a pedagogical introduction to Bose–Einstein condensation in traps with
spherical symmetry, namely, the spherical box and the thick shell, sometimes called bubble …

In this thesis the dynamics of ultracold Rydberg gases under the influence of long-range
interactions is investigated, with regard to both the incoherent motion of the atoms and …

The subject of this thesis is the investigation of the stability and the collapse dynamics of a
dipolar 52Cr Bose-Einstein condensate (BEC) in a one-dimensional (1D) optical lattice …

Actualmente el estudio de gases ultrafríos confinados en trampas atómicas es de gran
relevancia en el campo de la física atómica y molecular. Los gases atómicos ultrafríos se …

This text corresponds to part of the course presented at the ELAF XXXVIII. It is composed of
work previously done along the years. The level of this introduction follows the last year of …

The physics of ultracold quantum gases has been the subject of a long-lasting and intense
research activity, which started almost a century ago with purely theoretical studies and had …

In the last years, it has been shown that ultracold atomic gases provide an'ideal'environment
for studying many-body quantum systems usually encountered in condensed matter physics …

We experimentally investigate how the collapse dynamics of a 52Cr Bose-Einstein
condensate depends on the external harmonic trap geometry. When the collapse is initiated …

Neste trabalho, utilizamos um condensado de Bose-Einstein de átomos de Rb, para
analisar o efeito de campos externos perturbatórios sobre a distribuição de população de …

In this thesis we have basically studied two aspects of BoseEinstein condensation (BEC) in
trapped dilute gases:(i) superfluidity with the possible onset of quantum turbulence (QT), and …
