Ground state and collective excitations of a dipolar Bose-Einstein condensate in a bubble trap
Pedro de Castro Diniz, Eduardo Amâncio Barbosa Oliveira, Aristeu Rosendo Pontes Lima +1
We consider the ground state and the low-lying excitations of dipolar Bose-Einstein condensates in a bubble trap, i.e., a shell-shaped spherically symmetric confining potential. By…
Ground state of an ultracold Fermi gas of tilted dipoles in elongated traps
Vladimir Veljic, Aristeu R. P. Lima, Lauriane Chomaz +5
Many-body dipolar effects in Fermi gases are quite subtle as they energetically compete with the large kinetic energy at and below the Fermi surface (FS). Recently it was experimen…
Bound vortex states and exotic lattices in multi-component Bose-Einstein condensates: The role of vortex-vortex interaction
Davi S. Dantas, Aristeu R. P. Lima, A. Chaves +3
We numerically study the vortex-vortex interaction in multi-component homogeneous Bose-Einstein condensates within the realm of the Gross-Pitaevskii theory. We provide strong evide…
Low-Lying Excitation Modes of Trapped Dipolar Fermi Gases: From Collisionless to Hydrodynamic Regime
F. Waechtler, A. R. P. Lima, A. Pelster
By means of the Boltzmann-Vlasov kinetic equation we investigate dynamical properties of a trapped, one-component Fermi gas at zero temperature, featuring the anisotropic and long-…
Gauge field localization on the Bloch Brane
W. T. Cruz, Aristeu R. P. Lima, C. A. S. Almeida
We present new results on the localization of gauge fields in thick brane models. The four-dimensional observable universe is considered to be a topological defect which is generat…
Beyond Mean-Field Low-Lying Excitations of Dipolar Bose Gases
Aristeu R. P. Lima, Axel Pelster
We theoretically investigate various beyond mean-field effects on Bose gases at zero temperature featuring the anisotropic and long-range dipole-dipole interaction in addition to t…
Quantum Fluctuations in Dipolar Bose Gases
Aristeu R. P. Lima, Axel Pelster
We investigate the influence of quantum fluctuations upon dipolar Bose gases by means of the Bogoliubov-de Gennes theory. Thereby, we make use of the local density approximation to…
Dipolar Fermi gases in anisotropic traps
Aristeu R. P. Lima, Axel Pelster
The quest for quantum degenerate Fermi gases interacting through the anisotropic and long-range dipole-dipole interaction is an exciting and fast developing branch within the cold-…
Collective Motion of Polarized Dipolar Fermi Gases in the Hydrodynamic Regime
Aristeu R. P. Lima, Axel Pelster
Recently, a seminal STIRAP experiment allowed the creation of 40K-87Rb molecules in the rovibrational ground state [K.-K. Ni et al., Science 322, 231 (2008)]. In order to describe…
