Solids and supersolids of three-body interacting polar molecules on an optical lattice.
We study the physics of cold polar molecules loaded into an optical lattice in the regime of strong three-body interactions, as put forward recently by Büchler et al. [Nature Phys. 3, 726 (2007)]. To this end, quantum Monte Carlo simulations, exact diagonalization, and a semiclassical approach are used to explore hard-core bosons on the 2D square lattice which interact solely by long-ranged thr...
متن کاملThree-body interactions with cold polar molecules
Fundamental interactions between particles, such as the Coulomb law, involve pairs of particles, and our understanding of the plethora of phenomena in condensed-matter physics rests on models involving effective two-body interactions. On the other hand, exotic quantum phases, such as topological phases or spin liquids, are often identified as ground states of hamiltonians with threeor more-body...
متن کاملMany-body dynamics of dipolar molecules in an optical lattice.
We use Ramsey spectroscopy to experimentally probe the quantum dynamics of disordered dipolar-interacting ultracold molecules in a partially filled optical lattice, and we compare the results to theory. We report the capability to control the dipolar interaction strength. We find excellent agreement between our measurements of the spin dynamics and theoretical calculations with no fitting param...
متن کاملStrongly Interacting Atoms and Molecules in a 3D Optical Lattice
We report on the realization of a strongly interacting quantum degenerate gas of fermionic atoms in a three-dimensional optical lattice. We prepare a bandinsulating state for a two-component Fermi gas with one atom per spin state per lattice site. Using a Feshbach resonance, we induce strong interactions between the atoms. When sweeping the magnetic field from the repulsive side towards the att...
متن کاملInteracting Bose Gas in an Optical Lattice
A grand canonical system of hard-core bosons in an optical lattice is considered. The bosons can occupy randomly N equivalent states at each lattice site. The limit N → ∞ is solved exactly in terms of a saddle-point integration, representing a weakly-interacting Bose gas. In the limit N → ∞ there is only a condensate if the fugacity of the Bose gas is larger than 1. Corrections in 1/N increase ...
