Exact Bond-Located Spin Ground State in the Hubbard Chain with Off-Diagonal Coulomb Interactions
Kazuhito Itoh, Masaaki Nakamura, Norihiro Muramoto
We show the existence of an exact ground state in certain parameter regimes of one-dimensional half-filled extended Hubbard model with site-off-diagonal interactions. In this groun…

Role of Bond-Bond Interaction in the Extended Hubbard Chain
Masaaki Nakamura, Kazuhito Itoh, Norihiro Muramoto
Phase diagrams of the one-dimensional extended Hubbard model with a nearest neighbor interaction and site-off-diagonal (bond-charge and bond-bond ) interactions at half-…

Integrable Magnetic Model of Two Chains Coupled by Four-Body Interactions
Norihiro Muramoto, Minoru Takahashi
An exact solution for an XXZ chain with four-body interactions is obtained and its phase diagram is determined. The model can be reduced to two chains coupled by four-body interact…
