    "abstract": "We demonstrate that in a triangular configuration of an optical lattice of\ntwo atomic species a variety of novel spin-1/2 Hamiltonians can be generated.\nThey include effective three-spin interactions resulting from the possibility\nof atoms tunneling along two different paths. This motivates the study of\nground state properties of various three-spin Hamiltonians in terms of their\ntwo-point and n-point correlations as well as the localizable entanglement. We\npresent a Hamiltonian with a finite energy gap above its unique ground state\nfor which the localizable entanglement length diverges for a wide interval of\napplied external fields, while at the same time the classical correlation\nlength remains finite.",
