Report on 1706.02421v2 Open
Using a perturbative renormalization group approach, we show that the extended (J 1 -J 2 -J d ) Heisenberg model on the kagome lattice with a staggered chiral interaction (J χ ) can exhibit a gapless chiral quantum spin liquid phase.Within…

Competition between spin liquids and valence-bond order in the frustrated spin- Heisenberg model on the honeycomb lattice Open
Using variational wave functions and Monte Carlo techniques, we study the antiferromagnetic Heisenberg model with first-neighbor J(1) and second-neighbor J(2) antiferromagnetic couplings on the honeycomb lattice. We perform a systematic co…

Chiral Spin Liquid on a Kagome Antiferromagnet Induced by the Dzyaloshinskii-Moriya Interaction Open
The quantum spin liquid material herbertsmithite is described by an antiferromagnetic Heisenberg model on the kagome lattice with a non-negligible Dzyaloshinskii-Moriya interaction (DMI). A well-established phase transition to the q=0 long…

Projective symmetry group classification of chiral spin liquids Open
We present a general review of the projective symmetry group classification\nof fermionic quantum spin liquids for lattice models of spin $S=1/2$. We then\nintroduce a systematic generalization of the approach for symmetric\n$\\mathbb{Z}_2…

Gapless chiral spin liquid in a kagome Heisenberg model Open
Motivated by recent experiments on the Heisenberg S=1/2 quantum spin liquid\ncandidate material kapellasite, we classify all possible chiral (time-reversal\nsymmetry breaking) spin liquids with fermionic spinons on the kagome lattice.\nWe …
