Turbulence, the complicated fluid behavior of nonlinear and statistical nature, arises in many
physical systems across various disciplines, from tiny laboratory scales to geophysical and …

Vorticity is a key ingredient to a broad variety of fluid phenomena, and its quantised version
is considered to be the hallmark of superfluidity. Circulating flows that correspond to vortices …

We experimentally observe the decay dynamics of deterministically created isolated
monopoles in spin-1 Bose-Einstein condensates. As the condensate undergoes a change …

Strongly localized vorticity is a key ingredient of a broad variety of fluid phenomena, and its
quantized version is considered to be the hallmark of superfluidity. Flows that correspond to …

Neste trabalho, estudamos o efeito da turbulência quântica na expansão livre do
condensado de Bose-Einstein de 87Rb. O BEC é produzido em uma armadilha magnética …

In this thesis, we present the generation and studies of a 87Rb Bose-Einstein condensate
(BEC) perturbed by an oscillatory excitation. The atoms are trapped in a harmonic magnetic …

In this thesis, we numerically investigate quantum turbulence in trapped atomic Bose-
Einstein condensates (BECs). We first discuss the appropriate qualitative characterization of …
