Bose-Einstein condensate in a quartic potential:static and dynamic properties

Chaudhary, G.K., Chattopadhyay, Amit and Ramakumar, R. Bose-Einstein condensate in a quartic potential:static and dynamic properties. International Journal of Modern Physics B, 25 (29), pp. 3927-3940.


In this paper, we present a theoretical study of a Bose-Einstein condensate of interacting bosons in a quartic trap in one, two, and three dimensions. Using Thomas-Fermi approximation, suitably complemented by numerical solutions of the Gross-Pitaevskii equation, we study the ground sate condensate density profiles, the chemical potential, the effects of cross-terms in the quartic potential, temporal evolution of various energy components of the condensate, and width oscillations of the condensate. Results obtained are compared with corresponding results for a bose condensate in a harmonic confinement.
