Absence of Translational Symmetry Breaking in Nonmagnetic Insulator Phase on Two-Dimensional Lattice with Geometrical Frustration
Shinji Watanabe, Masatoshi Imada
The ground-state properties of the two-dimensional Hubbard model with nearest-neighbor and next-nearest-neighbor hoppings at half filling are studied by the path-integral-renormali…

Quantum Phase Transitions to Charge Order and Wigner Crystal Under Interplay of Lattice Commensurability and Long-Range Coulomb Interaction
Yohei Noda, Masatoshi Imada
Relationship among Wigner crystal, charge order and Mott insulator is studied by the path-integral renormalization group method for two-dimensional lattices with long-range Coulomb…

Nonmagnetic Insulating States near the Mott Transitions on Lattices with Geometrical Frustration and Implications for -(ET)Cu
Hidekazu Morita, Shinji Watanabe, Masatoshi Imada
We study phase diagrams of the Hubbard model on anisotropic triangular lattices, which also represents a model for -type BEDT-TTF compounds. In contrast with mean-field predicti…
