Tunable Superfluidity and Quantum Magnetism with Ultracold Polar Molecules
(American Physical Society, 2011)
By selecting two dressed rotational states of ultracold polar molecules in an optical lattice, we obtain a highly tunable generalization of the \(t-J\) model, which we refer to as the \(t-J-V-W\) model. In addition to XXZ ...
Quantum Magnetism with Polar Alkali-Metal Dimers
(American Physical Society, 2011)
We show that dipolar interactions between ultracold polar alkali dimers in optical lattices can be used to realize a highly tunable generalization of the \(t-J\) model, which we refer to as the \(t-J-V-W\) model. The model ...
