Light-front Hamiltonian approach to the bound-state problem in quantum electrodynamics.

摘要

his dissertation presents the first theoretical investigation of the Lamb shift in a light-front hamiltonian approach: the dominant part of the splitting between the ;We study the QED bound-state problem in a light-front hamiltonian approach. We start from a canonical QED Hamiltonian, and set up a general formalism for deriving the effective Hamiltonian
