Number of vortices generated in a rotating Bose-Einstein condensates in two-dimensional optical lattice
In the present paper we calculate the number of vortices generated in a
rotating Bose-Einstein condensate in two-dimensional optical lattice.
Our approach enabled us to parametrize the vortices number in terms of the
thermodynamic potential for the system under consideration. The
thermodynamic potential is calculated using the semiclassical approximation
approach. The finite size and the interatomic interaction effects are
investigated. The calculated results show that the vortices number as a
function of the angular velocity of rotation rate depends on the normalized
temperature, number of particles, interatomic interaction, and optical
potential
