# Generalized yrast states of a Bose-Einstein condensate in a harmonic trap for a universality class of interactions

@article{Hussein2002GeneralizedYS, title={Generalized yrast states of a Bose-Einstein condensate in a harmonic trap for a universality class of interactions}, author={M. S. Hussein and Oleg K. Vorov}, journal={Physical Review A}, year={2002}, volume={65}, pages={035603} }

For a system of N bosons in a two-dimensional harmonic trap with frequency ω, interacting via forces V «∞ω, we develop a method to find the ground states of rotating Bose condensate as a function of two quantum numbers, the total angular momentum and the angular momentum of internal excitations (generalized yrast states). The energies of these condensed vortex states are expressed through the single two-body matrix element of interaction, V. A broad universality class of predominantly repulsive… Expand
