A self-consistent first-principles calculation scheme for correlated electron systems
Koichi Kusakabe, Naoshi Suzuki, Shusuke Yamanaka +1
A self-consistent calculation scheme for correlated electron systems is created based on the density-functional theory (DFT). Our scheme is a multi-reference DFT (MR-DFT) calculati…
MCSCF-DFT based on an interacting reference system
Shusuke Yamanaka, Koichi Kusakabe, Kazuto Nakata +2
We present the MCSCF version of density functional theory. Two sets of equations, which correspond to the CI and orbital relaxation respectively, are derived. An important feature…
Quantum Electrodynamical Density-matrix Functional Theory and Group-theoretical Consideration of its Solution
Tadafumi Ohsaku, Shusuke Yamanaka, Daisuke Yamaki +1
For studying the group theoretical classification of the solutions of the density functional theory in relativistic framework, we propose quantum electrodynamical density-matrix fu…
