Bose-Hubbard model in a ring-shaped optical lattice with high filling factors
H. M. Cataldo, D. M. Jezek
The high-barrier quantum tunneling regime of a Bose-Einstein condensate confined in a ring-shaped optical lattice is investigated. By means of a change of basis transformation, con…

Winding number dependence of Bose-Einstein condensates in a ring-shaped lattice
D. M. Jezek, H. M. Cataldo
We study the winding number dependence of the stationary states of a Bose-Einstein condensate in a ring-shaped lattice. The system is obtained by confining atoms in a toroidal trap…
