Zoller. 2007. “Strongly Correlated 2D Quantum Phases with Cold Polar Molecules: Controlling the Shape of the Interaction Potential.” Physical Review Letters 98 (6) (February 8). doi:10.1103/physrevlett.98.060404.0031-9007http://nrs.harvard.edu/urn-3:HUL.InstRepos:27891922We 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.en-USJournal Article2016-08-2410.1103/physrevlett.98.060404
