    "abstract": "The entanglement properties of some novel quantum systems are studied that\nare inspired by recent developments in cold-atom technology. A triangular\noptical lattice of two atomic species can be employed to generate a variety of\nspin-1/2 Hamiltonians including effective three-spin interactions. A variety of\none or two dimensional systems can thus be realized that possess\nmulti-degenerate ground states or non-vanishing chirality. The properties of\nthese ground states and their phase transitions are probed with appropriate\nmeasures such as the entropic entanglement and the spin chirality.",
