    "abstract": "We describe how to design a large class of always on spin-1 interactions\nbetween polar molecules trapped in an optical lattice. The spin degrees of\nfreedom correspond to the hyperfine levels of a ro-vibrational ground state\nmolecule. Interactions are induced using a microwave field to mix ground states\nin one hyperfine manifold with the spin entangled dipole-dipole coupled excited\nstates. Using multiple fields anistropic models in one, two, or three\ndimensions, can be built with tunable spatial range. An illustrative example in\none dimension is the generalized Haldane model, which at a specific parameter\nhas a gapped valence bond solid ground state. The interaction strengths are\nlarge compared to decoherence rates and should allow for probing the rich phase\nstructure of strongly correlated systems, including dimerized and gapped\nphases.",
