An Evaluation of Critical Frequency of Vortex as a Function of Number of Atoms N in Bose Einstein Condensates

Gajendra Prasad Gadker and Lal

Abstract

In this paper, we have presented a method of evaluation of critical frequent Ωc of vortex whose circulation number k = 1 confined in a spherical trap with N atoms of 87Rb. We have taken the values of ah0 = 0.791 μm. Our k =1 theoretically evaluated results indicate that Ωc decreases with N and decrease is more pronounced as one goes to higher N. Our theoretical results are consistent with those of the others theoretical workers.
