DESCRIPTION METHOD FOR NONPERTURBATIVE ATOMIC NUCLEUS/ELECTRONIC SYSTEM BASED ON RELATIVISTIC QUANTUM FIELD THEORY

摘要

PROBLEM TO BE SOLVED: To provide a method not only for allowing integral handling, which cannot be performed in a conventional calculation method, of both worlds of an atomic nucleus hierarchy and an electron system but also for nonperturbatively calculating a basic value of substance behavior/characteristics by automatically introducing effect of higher order correlation between a nucleon and an electron based on a relativistic field quantum theory.;SOLUTION: Using relativistic Lagrangian densities of both of the atomic nucleus hierarchy and the electron system hierarchy as starting points, a field equation is derived to be separated into classical field calculation and quantum field calculation. In a classical field (mean field), a substance structure is introduced, while the quantum field gives quantum correction from the mean classical field. An equation for the quantum field is separated into propagation functions of a nucleon and antinucleon, a positron and an electron, a positive hole, and the like, each self-energy, self-energy of a meson or photon, and a propagation function to be concretely given by integral display. In this way, characteristics of a substance ranging from an atomic nucleus to an atom or a polymer can be precisely and nonperturbatively calculated.;COPYRIGHT: (C)2007,JPO&INPIT
