Free expansion of Bose-Einstein condensates with a multicharged vortex
Rafael Poliseli Teles, F. E. A. dos Santos, M. A. Caracanhas +1
In this work, we analyze the free expansion of Bose-Einstein condensates containing multicharged vortices. The atomic cloud is initially confined in a three-dimensional asymmetric…
Dynamics of the relativistic Gross-Pitaevskii equation with harmonic potential: Following the variational approach
R. P. Teles, F. J. Poveda-Cuevas
The role of the collective excitations as well as the free expansion dynamics provide a key diagnostic tools for trapped Bose-Einstein condensations. Based on such dynamics we prop…
Stability change of a multi-charged vortex due to coupling with quadrupole mode
Rafael Poliseli Teles, Francisco Ednilson Alves dos Santos, Vanderlei Salvador Bagnato
We have studied collective modes of quasi-2D Bose-Einstein condensates with multiply-charged vortices using a variational approach. Two of the four collective modes considered exhi…
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…
