We use variational Monte Carlo techniques to calculate the energies of microscopic spin liquid wave functions where spin is represented by three flavors of fermionic spinon operators. These energies are compared with the energies of various competing three-sublattice ordered states. Our approach shows that the antiferromagnetic Heisenberg model with biquadratic term and single-ion anisotropy does not have a low-temperature spin liquid phase. However, for an SU(3)-invariant model with sufficiently strong ring-exchange terms, we find a paired chiral quantum spin liquid with a Fermi surface of deconfined spinons that is stable against all types of ordering patterns we considered. We discuss the physics of this exotic spin liquid state in relation to the recent experiment and suggest new ways to test this scenario.","lang":"eng"}],"main_file_link":[{"url":"https://arxiv.org/abs/1208.3231","open_access":"1"}],"date_published":"2012-12-13T00:00:00Z","citation":{"mla":"Bieri, Samuel, et al. “Paired Chiral Spin Liquid with a Fermi Surface in S=1 Model on the Triangular Lattice.” <i>Physical Review B - Condensed Matter and Materials Physics</i>, vol. 86, no. 22, American Physical Society, 2012, doi:<a href=\"https://doi.org/10.1103/PhysRevB.86.224409\">10.1103/PhysRevB.86.224409</a>.","ieee":"S.
