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

Afshan Suraiya and Lalit Kumar Mishra

In this paper, we have presented a method of evaluation of critical frequent Ωc of vortex whose circulation number к = 1 confined in a spherical trap with N atoms of 87Rb. We have taken the values of ah0 = 0.791 μm. Ourtheoretically 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.
