Chiral spin liquid on kagome antiferromagnet induced by Dzyaloshinskii-Moriya interaction
Laura Messio, Samuel Bieri, Claire Lhuillier +1
The quantum spin liquid material herbertsmithite is described by an antiferromagnetic Heisenberg model on the kagome lattice with non-negligible Dzyaloshinskii-Moriya interaction~(…
Projective symmetry group classification of chiral spin liquids
Samuel Bieri, Claire Lhuillier, Laura Messio
We present a general review of the projective symmetry group classification of fermionic quantum spin liquids for lattice models of spin . We then introduce a systematic gen…
Gapless chiral spin liquid in a kagome Heisenberg model
Samuel Bieri, Laura Messio, Bernard Bernu +1
Motivated by recent experiments on the Heisenberg S=1/2 quantum spin liquid candidate material kapellasite, we classify all possible chiral (time-reversal symmetry breaking) spin l…
Spin susceptibility of quantum magnets from high to low temperatures
B. Bernu, C. Lhuillier
We present a method to compute the magnetic susceptibility of spin systems at all temperatures in one and two dimensions. It relies on an approximation of the entropy versus energy…
Time-reversal-symmetry-breaking chiral spin liquids: a projective symmetry group approach of bosonic mean-field theories
Laura Messio, Claire Lhuillier, Grégoire Misguich
Projective symmetry groups (PSG) are the mathematical tools which allow to list and classify mean-field spin liquids (SL) based on a parton construction. The seminal work of Wen an…
Exchange energies of Kapellasite from high-temperature series analysis of the kagome lattice J1-J2-Jd-Heisenberg model
B. Bernu, C. Lhuillier, E. Kermarrec +4
We present a method to build magnetic models for insulators based on high-temperature expansions by fitting both the magnetic susceptibility and the low temperature specific heat d…
