# Electron spectral functions in a quantum dimer model for topological metals

@article{Huber2018ElectronSF, title={Electron spectral functions in a quantum dimer model for topological metals}, author={Sebastian D. Huber and John Feldmeier and Matthias Punk}, journal={Physical Review B}, year={2018}, volume={97} }

We study single electron spectral functions in a quantum dimer model introduced by Punk, Allais and Sachdev (Ref. [1]). The Hilbert space of this model is spanned by hard-core coverings of the square lattice with two types of dimers: ordinary bosonic spin-singlets, as well as fermionic dimers carrying charge +e and spin 1/2, which can be viewed as bound-states of spinons and holons in a doped resonating valence bond (RVB) liquid. This model realizes a metallic phase with topological order and…
