Ferromagnetic phase in the polarized two-species bosonic Hubbard Model
Kalani Hettiarachchilage, Valéry G. Rousseau, Ka-Ming Tam +2
We recently studied a doped two-dimensional bosonic Hubbard model with two hard-core species, with different masses, using quantum Monte Carlo simulations [Phys. Rev. B 88, 161101(…
Complex phases in the doped two-species bosonic Hubbard Model
Kalani Hettiarachchilage, Valéry G. Rousseau, Ka-Ming Tam +2
We study a two-dimensional bosonic Hubbard model with two hard-core species away from half filling using Quantum Monte Carlo simulations. The model includes a repulsive interspecie…
Phase diagram of the Bose-Hubbard model on a ring-shaped lattice with tunable weak links
Kalani Hettiarachchilage, Valéry G. Rousseau, Ka-Ming Tam +2
Motivated by recent experiments on toroidal Bose-Einstein condensates in all-optical traps with tunable weak links, we study the one-dimensional Bose-Hubbard model on a ring-shaped…
Using off-diagonal confinement as a cooling method
V. G. Rousseau, K. Hettiarachchilage, M. Jarrell +2
In a recent letter [Phys. Rev. Lett. 104, 167201 (2010)] we proposed a new confining method for ultracold atoms on optical lattices, based on off-diagonal confinement (ODC). This m…
