Strongly interacting one-dimensional Bose-Einstein condensates in harmonic traps
Physical Review A. Atomic, Molecular, and Optical Physics
We study the interaction effects on the condensates by considering a model of one-dimensional bosons. The harmonic external potential allows for the formation of a condensate in these systems. Using a densityfunctional theory-type formalism we obtain an equation describing the condensate wave function in the limit of very strong interactions between the bosons. We then consider a model of strongly interacting two-component system of bosons and study its stability conditions. Similar to thedoi:10.1103/physreva.62.053601 fatcat:5tqtbbiuurhaneg3bfasmd7h2u
