APPLICATION OF φ~4-THEORY ON STARK EFFECT AND ZEEMAN EFFECT OF THE HYDROGEN ATOM
Chen Hao · Journal of South China Normal University · 2007
The hydrogen atom in the Stark effect and Zeeman effect is mapped into the four-dimensional anisotropican harmonic oscillator by the Green function.The Symmetry Factor of four loops Vacuum Diagram is given.The tensor of Multicomponent φ4 field is introduced to calculate the new case of Multicomponent φ4×φ2 field in the Zeeman effect.The four-order perturbation expansion of the ground state is studied by the mean of Multicomponent Field Symmetry Factor and!Feynman Diagram.It is suggested that the φ4-theory can be the new tool for the study of Coulomb system.
