Ground state and thermal transitions in Field Induced spin-Supersolid Phase
Abstract
We use a quantum Monte Carlo method to study the ground state and thermodynamic phase transitions of the spin supersolid phase in the S=1 Heisenberg model with uniaxial anisotropy. The thermal melting of the supersolid phase shows unqiue signatures in experimentally measurable observables. This Hamiltonian is a particular case of a more general and ubiquitous model that describes the low energy spectrum of a class of isotropic and frustrated spin systems. We also discuss some alternative realizations of spin supersolid states in real magnets.
