Quantum field theory

The "Lee model" was founded in 1954, which is of far-reaching significance for the study of field theory and renormalization [1]. After that, in the 1960s, Lee cooperated with G.C. wick and found that the unitarity of S matrix under indefinite gauge has violated the causality [4]

The KLN (Kinoshita-Lee-Nauenberg) theorem is an indispensable theorem in strong interaction experiments, and it is also the theoretical basis for discovering quarks and gluons in high-energy jets. [2]

Gradually construct the field algebra theory in a series of studies .[3]

Proposed a quantum electrodynamics theory with relativistic invariance, gauge invariance, unitary and free from divergences. [5]

Established a new research field of non-topological solitons, and then established the soliton model of hadrons. [6]

Random lattice theory is proposed, solved the fermion-doubling spectrum problem in lattice gauge theory, and the violation of translational and rotational invariance. [7]
