Comment on "Regional Versus Global Entanglement in Resonating-Valence-Bond States"
Fabien Alet, Daniel Braun, Grégoire Misguich
In a recent Letter [Phys. Rev. Lett. 99, 170502 (2007); quant-ph/0703227], Chandran and coworkers study the entanglement properties of valence bond (VB) states. Their main result i…
Quantum spin liquids
Gregoire Misguich
These notes are an introduction to a few selected theoretical ideas in the field of quantum spin liquids: classical zero modes and breakdown of the 1/S expansion, the Lieb-Schultz-…
Thermal destruction of chiral order in a two-dimensional model of coupled trihedra
Laura Messio, Jean-Christophe Domenge, Claire Lhuillier +3
We introduce a minimal model describing the physics of classical two-dimensional (2D) frustrated Heisenberg systems, where spins order in a non-planar way at T=0. This model, consi…
Correlations and order parameter at a Coulomb-crystal phase transition in a three-dimensional dimer model
Gregoire Misguich, Vincent Pasquier, Fabien Alet
The three-dimensional classical dimer model with interactions shows an unexpected continuous phase transition between an ordered dimer crystal and a Coulomb liquid. A detailed anal…
