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 ...
Photonic Phase Gate via an Exchange of Fermionic Spin Waves in a Spin Chain
(American Physical Society, 2010)
We propose a new protocol for implementing the two-qubit photonic phase gate. In our approach, the pi phase is acquired by mapping two single photons into atomic excitations with fermionic character and exchanging their ...
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 ...
Two-orbital SU(N) magnetism with ultracold alkaline-earth atoms
(Nature Publishing Group, 2010)
Fermionic alkaline-earth atoms have unique properties that make them attractive candidates for the realization of atomic clocks and degenerate quantum gases. At the same time, they are attracting considerable theoretical ...
