Collective excitation frequencies and vortices of a Bose-Einstein condensed state with gravity-like interatomic attraction
Tarun Kanti Ghosh
We study the collective excitations of a neutral atomic Bose-Einstein condensate with gravity-like interatomic attraction induced by electromagnetic wave. Using the time-dep…

Splitting between quadrupole modes of dilute quantum gas in a two dimensional anisotropic trap
Tarun Kanti Ghosh, Subhasis Sinha
We consider quadrupole excitations of quasi-two dimensional interacting quantum gas in an anisotropic harmonic oscillator potential at zero temperature. Using the time-dependent va…
