On the Triviality of Textbook Quantum Electrodynamics


By adding a small, irrelevant four fermi interaction to the action of lattice Quantum Electrodynamics (QED), the theory can be simulated with massless quarks in a vacuum free of lattice monopoles. This allows an ab initio high precision, controlled study of the existence of ”textbook” Quantum Electrodynamics with several species of fermions. The lattice… (More)
