Findings

Thermal melting shows unique signatures in measurable observables.

The model relates to a broader class of isotropic and frustrated spin systems.

Alternative realizations of spin supersolids in real magnets are discussed.

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 {\it isotropic} and {\it frustrated} spin systems. We also discuss some alternative realizations of spin supersolid states in real magnets.
