. The eigen-values and eigen-vectors for individual molecules obtained by block diagonalization of the original Hamiltonian, are sufficient to predict the next step of the reaction. The polarizabilities in the ordinary perturbation treatment is also effectively used. This procedure is further clarified by defining the effective coupling. The method is applied to a molecular compound between ethylene and H2.

een’s function method. The lattice, in this case, means the conduction electrons and the interaction is mainly due to the Fermi contact term. Electrons and nuclei are treated on the same footing, namely both are in the second quantized form. The coherent terms are summarized in a general fashion at the beginning.

heory. The classical Schrödinger field of an electron is assumed to be a Grassmann algebra. The interaction with a radiation field is introduced through the gauge field theory. In the Nambu representation, the Lagrangian of the system is invariant under the rotation about the z axis in the spin space, so that the Goldstone theorem suggests that the condensation occurs on the x–y plane. In the absence of any external field, the system is invariant under the phase transformation. This symmetry breaks due to the condensation, and then the massless Goldstone boson which is the supercurrent will follow. The presence of the photon field, however the photon field itself becomes massive due to the gauge symmetry breaking (Higgs phenomenon), which is the Messner effect.
