Three-spin interactions in optical lattices and criticality in cluster Hamiltonians.
We demonstrate that in a triangular configuration of an optical lattice of two atomic species a variety of novel spin-1/2 Hamiltonians can be generated. They include effective three-spin interactions resulting from the possibility of atoms tunneling along two different paths. This motivates the study of ground state properties of various three-spin Hamiltonians in terms of their two-point and n...
متن کاملThree-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 ...
متن کاملControlling spin exchange interactions of ultracold atoms in optical lattices.
We describe a general technique that allows one to induce and control strong interaction between spin states of neighboring atoms in an optical lattice. We show that the properties of spin exchange interactions, such as magnitude, sign, and anisotropy, can be designed by adjusting the optical potentials. We illustrate how this technique can be used to efficiently "engineer" quantum spin systems...
متن کاملSpin-exchange interactions of spin-one bosons in optical lattices: Singlet, nematic, and dimerized phases
We consider insulating phases of cold spin-1 bosonic particles with antiferromagnetic interactions, such as Na, in optical lattices. We show that spin-exchange interactions give rise to several distinct phases, which differ in their spin correlations. In twoand three-dimensional lattices, insulating phases with an odd number of particles per site are always nematic. For insulating states with a...
متن کاملThe equivalence between discrete-spin Hamiltonians and Ising Hamiltonians with multi-spin interactions
An argument is presented to explain the fact that the same mean-field results apply to several spin glass models, such as the 'random-energy' model and the large-p Potts glass model. The dilute simplest spin glass model is solved, yielding the same mean-field results. The argument is based on the fact that the symmetry of the discrete-spin system can be determined by the discrete-spin type or b...
