Electron density redistribution along chemical reaction coordinate has been studied by Professor Robert G. Parr and myself. The key issue in this study is the regional chemical potential inequality principle. The Onsager local equilibrium principle has then been applied to the Hohenberg-Kohn-Mermin density functional theories for the energy density concept. The ensemble of interest has been that of quantum mechanics. In the theoretical study on the application of quantum electrodynamics (QED), recent research progress has led to solve the mystery (as Feynman said) involved in the foundation of quantum mechanics. QED is a relativistic quantum field theory, a quantum theory of photons with electrons, and is considered the most successful accurate theory we have, e.g., to explain the Lamb shift, the anomalous magnetic moment of electron, and so on, using the Feynman diagram technique of the covariant perturbation approach. We shall elaborate then the non-perturbation approach of QED for the renewed energy density concept in this talk.
