Nonlinear dependence observed in quadrupolar collective excitation of a trapped BEC
A. R. Fritsch, P. E. S. Tavares, Y. R. Tonin +4
We report the experimental observation of the collective excitations induced in a magnetically trapped 87Rb Bose-Einstein condensate. Low-lying mode excitations were studied by tra…
Investigation of the momentum distribution of an excited BEC by free expansion: coupling with collective modes
A. Bahrami, P. E. S Tavares, A. R. Fritsch +4
We investigate the evolution of the momentum distribution of a Bose-Einstein condensate subjected to an external small oscillatory perturbation as a function of the in-trap evoluti…
Twisted unwinding of multi-charged quantum vortex and generation of turbulence in atomic Bose-Einstein condensates
G. D. Telles, P. E. S. Tavares, A. R. Fritsch +5
We report the observation of the twisted decay of quadruply charged vortices in an atomic Bose-Einstein condensate. Supporting numerical simulations show that the singly-charged vo…
