    "abstract": "We investigate the method to combine the techniques of quantum chemisty with\nQED. In our theory, we treat the N-electron system and the Dirac sea on an\nequal footing; we regard both of them as the dynamical degrees of freedom of a\nmany-body system. After the introduction of our QED-SCF method, the QED-SCF\nsolutions are classified into several classes on the basis of group-theoretical\noperations such as time reversal, parity and O(3) rotational symmetry. The\nnatural orbitals of general QED-SCF solutions are determined by diagonalizing\nthe first order density matrix. Thus, we obtain the possibility to treat the\nsystem under strong QED effect by the methods of quantum chemistry, such as\nQED-MCSCF and QED-coupled-cluster approaches.",
