abstract: 'We have constructed a LDA+DMFT method in the framework of the iterative perturbation theory (IPT) with full LDA Hamiltonian without mapping onto the effective Wannier orbitals. We then apply this LDA+DMFT method to ferromagnetic bcc-Fe and fcc-Ni as a test of transition metal, and to antiferromagnetic NiO as an example of transition metal oxide. In Fe and Ni, the width of occupied 3d bands is narrower than those in LDA and Ni $6~{\mbox{eV}}$ satellite appears. In NiO, the resultant electronic structure is of charge-transfer insulator type and the band gap is $4.3~{\mbox{eV}}$. These results are in good agreement with the experimental XPS. The configuration mixing and dynamical correlation effects play a crucial role in these results.'

Introduction
============

Much attention has been focused on strongly correlated electron systems, since these systems show anomalous physical properties such as various spin, charge and orbital order, metal-insulator transition and so on. The local density approximation (LDA) based on the density functional theory (DFT) is hardly applicable to these fruitful physical properties in strongly correlated electron
