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…

Tuning the Quantum Phase Transition of Bosons in Optical Lattices via Periodic Modulation of s-Wave Scattering Length
Tao Wang, Xue-Feng Zhang, Francisco Ednilson Alves dos Santos +2
We consider interacting bosons in a 2D square and a 3D cubic optical lattice with a periodic modulation of the s-wave scattering length. At first we map the underlying periodically…
