Quantum turbulence in trapped atomic Bose-Einstein condensates
Marios C. Tsatsos, Pedro E. S. Tavares, Andre Cidrim +5
Turbulence, the complicated fluid behavior of nonlinear and statistical nature, arises in many physical systems across various disciplines, from tiny laboratory scales to geophysic…
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…
