Effect of Doublon-Holon Binding on Mott transition---Variational Monte Carlo Study of Two-Dimensional Bose Hubbard Models
Hisatoshi Yokoyama, Tomoaki Miyagawa, Masao Ogata
To understand the mechanism of Mott transitions in case of no magnetic influence, superfluid-insulator (Mott) transitions in the S=0 Bose Hubbard model at unit filling are studied…

Effects of Long-Range Correlations on Nonmagnetic Mott Transitions in Hubbard model on Square Lattice
Tomoaki Miyagawa, Hisatoshi Yokoyama
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 variation…
