Quantum spin models with long-range interactions and tunnelings: a quantum Monte Carlo study

Quantum spin models with long-range interactions and tunnelings: a quantum Monte Carlo study

We use a quantum Monte Carlo method to investigate various classes of two-dimensional spin models with long-range interactions at low temperatures. In particular, we study a dipolar XXZ model with U (1) symmetry that appears as a hard-core boson limit of an extended Hubbard model describing polarize...
