Spin gap and string order parameter in the ferromagnetic Spiral Staircase Heisenberg Ladder: a quantum Monte Carlo study
C. Brünger, F. F. Assaad, S. Capponi +3
We consider a spin-1/2 ladder with a ferromagnetic rung coupling J_\perp and inequivalent chains. This model is obtained by a twist (θ) deformation of the ladder and interpolates b…
Criticality of a classical dimer model on the triangular lattice
F. Trousselet, P. Pujol, F. Alet +1
We consider a classical interacting dimer model which interpolates between the square lattice case and the triangular lattice case by tuning a chemical potential in the diagonal bo…
Valence Bond Entanglement Entropy
Fabien Alet, Sylvain Capponi, Nicolas Laflorencie +1
We introduce for SU(2) quantum spin systems the Valence Bond Entanglement Entropy as a counting of valence bond spin singlets shared by two subsystems. For a large class of antifer…
