Mixture of two ultra cold bosonic atoms confined in a ring: stability and persistent currents
E. T. D. Matsushita, E. J. V. de Passos
In this article we investigate the stability of quantized yrast (QY) states in a mixture of two distinguishable equal mass bosonic atoms, and , confined in a ring. We focus…

Superfluid to normal fluid phase transition in the Bose gas trapped in two dimensional optical lattices at finite temperature
M. O. C. Pires, E. J. V. de Passos
We develop the Hartree-Fock-Bogoliubov theory at finite temperature for Bose gas trapped in the two dimensional optical lattices. The on-site energy is considered low enough that t…
