Controlling polar molecules in optical lattices (A04)

• Subject Area: Optics, Quantum Optics and Physics of Atoms, Molecules and Plasmas
• Term: since 2016
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 274200144

Experiments on dipoles in optical lattices and tweezers open exciting new possibilities for the study of many-body quantum systems due to the strong inter-site dipolar interactions. A04 focuses on two types of lattice models that maybe simulated using dipolar gases, and in particular polar molecules. On one hand, we will study spin models, in which dipolar particles with two internal states are pinned at the lattice sites, especially focusing on out-of-equilibrium dynamics. On the other hand, we will investigate extended Hubbard models, where polarised dipolar particles do tunnel to nearest neighbors, paying special attention to realistic scenarios for the creation of ground-state phases, and to the effects of dipole-assisted hopping. This project will be carried in close collaboration with other projects.
