Query: Three-spin interactions and entanglement in optical lattices   The entanglement properties of some novel quantum systems are studied that
are inspired by recent developments in cold-atom technology. A triangular
optical lattice of two atomic species can be employed to generate a variety of
spin-1/2 Hamiltonians including effective three-spin interactions. A variety of
one or two dimensional systems can thus be realized that possess
multi-degenerate ground states or non-vanishing chirality. The properties of
these ground states and their phase transitions are probed with appropriate
measures such as the entropic entanglement and the spin chirality.
