Phase diagram of an extended quantum dimer model on the hexagonal latticeThiago Milanetto Schlittler1, •Thomas Barthel2, Grégoire Misguich3, Julien Vidal1, and Rémy Mosseri11LPTMC, Université Paris-6 — 2LPTMS, Université Paris-Sud — 3IPhT, CEA Saclay

We introduce a generalized quantum dimer model on the hexagonal lattice. In addition to the standard Rokhsar-Kivelson Hamiltonian, it contains a competing potential term. The phase diagram is studied by means of quantum Monte-Carlo simulations, variational ansätze and perturbation theory. The model displays a rich phase diagram and, in particular, provides a microscopic realization for the Cantor deconfinement scenario – a cascade of phases with varying flux.
