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…
1-Dimensional behavior and sliding Luttinger liquid phase in a frustrated spin-1/2 crossed chain model: contribution of exact diagonalizations
P. Sindzingre, J. -B. Fouet, C. Lhuillier
Exact diagonalizations indicate that the effective 1-dimensional behavior (sliding Luttinger liquid phase) of the frustrated spin-1/2 crossed chain model, predicted by Starykh, Sin…
Degeneracy of the ground-state of antiferromagnetic spin-1/2 Hamiltonians
G. Misguich, C. Lhuillier, M. Mambrini +1
In the first part of this paper, the extension of the Lieb-Schultz-Mattis theorem to dimensions larger than one is discussed. A counter example to the original formulation of Lieb-…
Quantum phases in two-dimensional frustrated spin-1/2 antiferromagnets
P. Sindzingre, C. Lhuillier, J. -B. Fouet
We describe four phases found in two-dimensional quantum antiferromagnets. Two of them display long range order at T=0: the Néel state and the Valence Bond Crystal. The last two ar…
An investigation of the quantum model on the honeycomb lattice
J. B. Fouet, P. Sindzingre, C. Lhuillier
We have investigated the quantum model on the honeycomb lattice with exact diagonalizations and linear spin-wave calculations for selected values of , $J…
Exact diagonalization Studies of Two-dimensional Frustrated Antiferromagnet Models
C. Lhuillier, P. Sindzingre, J. -B. Fouet
We describe the four kinds of behavior found in two-dimensional isotropic quantum antiferromagnets. Two of them display long range order at T=0: the Néel state and the Valence Bond…
