Strongly correlated 2D quantum phases with cold polar molecules: controlling the shape of the interaction potential
arXiv:cond-mat/0607294 · doi:10.1103/PhysRevLett.98.060404
Abstract
We discuss techniques to tune and shape the long-range part of the interaction potentials in quantum gases of polar molecules by dressing rotational excitations with static and microwave fields. This provides a novel tool towards engineering strongly correlated quantum phases in combination with low dimensional trapping geometries. As an illustration, we discuss a 2D crystalline phase, and a superfluid-crystal quantum phase transition.
