Phase diagram and magnetic excitations of anisotropic spin-one magnets

Phase diagram and magnetic excitations of anisotropic spin-one magnets

We use a generalized spin wave approach and large scale quantum Monte Carlo (QMC) simulations to study the quantum phase diagram and quasiparticle excitations of the S=1 Heisenberg model with an easy-plane single-ion anisotropy in dimensions d=2 and 3. We consider two alternative approximations for...
