Continuous interpolation between the fully frustrated Ising and quantum dimer models
arXiv:1102.1912 · doi:10.1103/PhysRevB.83.235129
Abstract
We propose a new quantum model interpolating between the fully frustrated spin-1/2 Ising model in a transverse field and a dimer model. This model contains a resonating-valence-bond phase, including a line with an exactly solvable ground state of the Rokhsar-Kivelson type. We discuss the phase diagrams of this model on the square and triangular (in terms of the dimer representation) lattices.
