A bound state is found in the strongly correlated electron system described by the Hubbard model. The state is the singlet state of correlated electrons and the binding energy of the state is estimated as 0.03 times the half band width in the case that the band is nearly half-filled by electrons.

We study the ground state properties of the one-dimensional extended-Hubbard-Kondo model at quarter-filling. This model captures the essential feature of the p-d system of organic conductors where the strongly correlated electrons interact with localized S ¼ 1 2 spins to bear interesting physics. It
Various types of ground states in strongly correlated electron systems have been systematically investigated by means of NMR/NQR at low temperatures under high magnetic field and pressure. We focus on two well-known heavy-electron families, CeCu2X 2 (X = Si and Ge) (Ce(122)) and UM2AI 3 (M = Ni and
