Tunable Superfluidity and Quantum Magnetism with Ultracold Polar Molecules
Tunable Superfluidity Quantum Magnetism Ultracold Polar Molecules
2011/9/13
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 a...

Twisted Hubbard Model for Sr2IrO4: Magnetism and Possible High Temperature Superconductivity
Twisted Hubbard Model for Sr2IrO4 Magnetism Possible High Temperature Superconductivity
2010/11/23
Sr2IrO4 has been suggested as a Mott insulator from a single Jeff = 1/2 band, similar to the
cuprates. However this picture is complicated by the measured large magnetic anisotropy and
ferromagnetis...
