Bose-Einstein condensates and the thin-shell limit in anisotropic bubble traps
Elias J. P. Biral, Natália S. Móller, Axel Pelster +1
Within the many different models that appeared with the use of cold atoms to design BECs the bubble trap shaped potential has been of great interest. For the anisotropic bubble tra…
Emergence of damped-localized excitations of the Mott state due to disorder
R. S. Souza, Axel Pelster, F. E. A. dos Santos
A key aspect of ultracold bosonic quantum gases in deep optical lattice potential wells is the realization of the strongly interacting Mott insulating phase. Many characteristics o…
Incompressible Energy Spectrum from Wave Turbulence
Marcos A. G. dos Santos Filho, Francisco E. A. dos Santos
Bose-Einstein condensates with their superfluidity property provide an interesting parallel to classical fluids. Due to the Kolmogorov spectrum of homogeneous turbulence the statis…
Vortices in self-bound dipolar droplets
André Cidrim, Francisco E. A. dos Santos, Emanuel A. L. Henn +1
Quantized vortices have been observed in a variety of superfluid systems, from He to condensates of alkali-metal bosons and ultracold Fermi gases along the BEC-BCS crossover. I…
Controlled polarization of two-dimensional quantum turbulence in atomic Bose-Einstein condensates
A. Cidrim, F. E. A. dos Santos, L. Galantucci +2
We propose a scheme for generating two-dimensional turbulence in harmonically trapped atomic condensates with the novelty of controlling the polarization (net rotation) of the turb…
Internal Decoherence of a Gaussian Wave Packet in a Harmonic Potential
A. Cidrim, F. E. A. dos Santos, A. O. Caldeira
We have studied the quantum dissipative problem of a Gaussian wave packet under the influence of a harmonic potential. A phenomenological approach to dissipation is adopted in the…
Coupling vortex dynamics with collective excitations in Bose-Einstein Condensates
R. P. Teles, V. S. Bagnato, F. E. A. dos Santos
Here we analyze the collective excitations as well as the expansion of a trapped Bose-Einstein condensate with a vortex line at its center. To this end, we propose a variational me…
