Photon embryology is suggested as a concept for a new branch of atomic physics or photon physics. Its theoretical system and research methods are discussed. It is stated that photon embryology is of great importance for the theoretical development of atomic physics, quantum optics, quantum mechanics and quantum information science and technology and their practice.

Abstract This review article presents historical developments and recent advances in our understanding on the three-body forces and Efimov physics, from an interdisciplinary viewpoint encompassing nuclear physics and cold atoms. Theoretical attempts to elucidate the three-body force with the chiral effective field theory are explained, followed by an overview of experiments aimed at observing signatures of the nuclear three-body force. Some recent experimental and theoretical works in the field of cold atoms devoted to measuring and engineering three-body forces among atoms are also presented. As a phenomenon arising from the three-body effect, Efimov physics in both cold atoms and nuclear systems is reviewed.

This work presents a novel theoretical framework addressing a fundamental problem in atomic and quantum physics. We propose a new physical mechanism to resolve long-standing inconsistencies in the description of electron behavior within atoms, establishing a consistent physical picture that bridges classical electromagnetic principles and quantum mechanical observations. This work lays a foundational conceptual basis for further rigorous mathematical formalization, detailed theoretical derivation, and experimental validation, with the aim of formal publication in leading peer-reviewed physics journals.
