Description:
Author(s): Zhifeng Zhang, Keola Wierschem, Ian Yap, Yasuyuki Kato, Cristian D. Batista, and Pinaki Sengupta 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 ... [Phys. Rev. B 87, 174405] Published Fri May 03, 2013
