Jastrow theory of the Mott transition in bosonic Hubbard models
Manuela Capello, Federico Becca, Michele Fabrizio +1
We show that the Mott transition occurring in bosonic Hubbard models can be successfully described by a simple variational wave function that contains all important long-wavelength…
Dynamics of the quantum dimer model on the triangular lattice: Soft modes and local resonating valence-bond correlations
Arnaud Ralko, Michel Ferrero, Federico Becca +2
We report on an exhaustive investigation of the dynamical dimer-dimer correlations in imaginary time for the quantum dimer model on the triangular lattice using the Green's functio…
Finite compressibility in the low-doping region of the two-dimensional model
Massimo Lugas, Leonardo Spanu, Federico Becca +1
We revisit the important issue of charge fluctuations in the two-dimensional model by using an improved variational method based on a wave function that contains both the a…
Identification of an RVB liquid phase in a quantum dimer model with competing kinetic terms
Francois Vernay, Arnaud Ralko, Federico Becca +1
Starting from the mean-field solution of a spin-orbital model of LiNiO, we derive an effective quantum dimer model (QDM) that lives on the triangular lattice and contains kinet…
Doping quantum dimer models on the square lattice
Didier Poilblanc, Fabien Alet, Federico Becca +3
A family of models is proposed to describe the motion of holes in a fluctuating quantum dimer background on the square lattice. Following Castelnovo et al. [Ann. Phys. (NY) 318, 31…
