Single hole and vortex excitations in the doped Rokhsar-Kivelson quantum dimer model on the triangular lattice
Hugo Ribeiro, Samuel Bieri, Dmitri Ivanov
We consider the doped Rokhsar-Kivelson quantum dimer model on the triangular lattice with one mobile hole (monomer) at the Rokhsar-Kivelson point. The motion of the hole is describ…

Crystallization of the resonating valence bond liquid as vortex condensation
Arnaud Ralko, Michel Ferrero, Federico Becca +2
We show that the liquid-to-crystal quantum phase transition in the Rokhsar--Kivelson dimer model on the two-dimensional triangular lattice occurs as a condensation of vortex-like e…

Coherent spectral weight of Gutzwiller-projected superconductors
Samuel Bieri, Dmitri Ivanov
We analyze the electronic Green's functions in the superconducting ground state of the t-J model using Gutzwiller-projected wave functions, and compare them to the conventional BCS…
