# Effects of Long-Range Correlations on Nonmagnetic Mott Transitions in Hubbard model on Square Lattice

@article{Miyagawa2011EffectsOL, title={Effects of Long-Range Correlations on Nonmagnetic Mott Transitions in Hubbard model on Square Lattice}, author={T. Miyagawa and Hisatoshi Yokoyama}, journal={arXiv: Strongly Correlated Electrons}, year={2011} }

The mechanism of Mott transition in the Hubbard model on the square lattice is studied without explicit introduction of magnetic and superconducting correlations, using a variational Monte Carlo method. In the trial wave functions, we consider various types of binding factors between a doubly-occupied site (doublon, D) and an empty site (holon, H), like a long-range type as well as a conventional nearest-neighbor type, and add independent long-range D-D (H-H) factors. It is found that a wide… Expand
