Frustrated Quantum Magnets
Claire Lhuillier
A description of different phases of two dimensional magnetic insulators is given. The first chapters are devoted to the understanding of the symmetry breaking mechanism in the sem…
Twelve sublattice ordered phase in the J1-J2 model on the kagome lattice
Jean-Christophe Domenge, Philippe Sindzingre, Claire Lhuillier +1
Motivated by recent experiments on an S=1/2 antiferromagnet on the kagome lattice, we investigate the Heisenberg J1-J2 model with ferromagnetic J1 and antiferromagnetic J2. Classic…
Two Step Restoration of SU(2) Symmetry in a Frustrated Ring-Exchange Magnet
A. Laeuchli, J. C. Domenge, C. Lhuillier +2
We demonstrate the existence of a spin-nematic, moment-free phase in a quantum four-spin ring exchange model on the square lattice. This unusual quantum state is created by the int…
Quantum dimer model with Z_2 liquid ground-state: interpolation between cylinder and disk topologies and toy model for a topological quantum-bit
Gregoire Misguich, Vincent Pasquier, Frederic Mila +1
We consider a quantum dimer model (QDM) on the kagome lattice which was introduced recently [Phys. Rev. Lett. 89, 137202 (2002)]. It realizes a Z_2 liquid phase and its spectrum wa…
Spin-1/2 antiferromagnets in 2 dimensions
C. Lhuillier, P. Sindzingre
The properties of the groundstate and first excitations of 2dimensionnal quantum antiferromagnets are rapidly sketched. A special emphasis is put on the gapped phases: Valence Bond…
Frustrated quantum magnets
Claire Lhuillier, Gregoire Misguich
In these lectures we sketch a rapid survey of recent theoretical advances in the study of frustrated quantum magnets with a special emphasis on two dimensional magnets.
