… The ground state of the periodic Anderson model on a triangular lattice is systematically investigated by mean-field approximation. … We found that the model exhibits two different types of partially disordered states: one is at half filling and the other is at other commensurate fillings. …

… We study an extended periodic Anderson model with the Coulomb interaction U_{c\aku f} between conduction and f electrons by the Gutzwiller method. … In the Kondo regime, a large enhancement in the effective mass occurs as in the ordinary periodic Anderson model without U_{c\aku f}. …

… We present a method to describe the quasi-particle bands of heavy-fermion Ce compounds on the basis of the periodic Anderson model taking account of the realistic conduction-band structures using the Wannier functions. …

… We report our theoretical results on the emergence of a partially disordered state at zero temperature and its detailed nature in the periodic Anderson model on a triangular lattice at half-filling. … The result demonstrates that the partially disordered state is observed distinctly even in the absence of spin anisotropy, in marked contrast to the partial Kondo screening state found in the previous study for the Kondo lattice model. …

We study the mechanism of the mass enhancement in an intermediate-valent regime of heavy-fermion materials. We find that the crossovers between the Kondo, intermediate valent, and almost empty f-elect …

… We investigate effect of an external magnetic field $h$ in an extended periodic Anderson model, which includes the repulsion $U_{cf}$ between $ f$ and conduction electron in a usual periodic Anderson model. … We treat the model with dynamical mean-field theory using an exact diagonalization method. …
