Slave boson model for two-dimensional trapped Bose-Einstein condensate
arXiv:cond-mat/0504267 · doi:10.1088/0953-4075/38/13/017
Abstract
A system of N bosons in a two-dimensional harmonic trap is considered. The system is treated in term of the slave boson representation for hard-core bosons which is valid in the arbitrary density regimes. I discuss the consequences of higher order interactions on the density profiles by mapping the slave boson equation to the known Kohn-Sham type equation within the density functional scheme.
