Projective symmetry group classification of chiral Z2 spin liquids on the pyrochlore lattice: Application to the spin- 12 XXZ Heisenberg model
Benedikt Schneider, Jad C. Halimeh, Matthias Punk
Simplified models for quantum spin-ice materials, such as the XXZ model on the pyrochlore lattice, may host interesting new spin-liquid ground states. In this work, the authors provide a complete classification of nearest-neighbor chiral ${\mathbb{Z}}_{2}$ spin-liquid states on the pyrochlore lattice using a projective symmetry group analysis. Moreover, the newly classified states are applied to the XXZ model within a self-consistent mean-field scheme. Observable signatures in neutron scattering experiments are discussed.
