Quenched QED on a momentum space lattice

Abstract

We discuss the advantages of using the momentum space lattice method for studying the phase diagram of quenched QED_4. Preliminary results of a numerical simulation are presented. They indicate that the method avoids the contamination by 4-fermi interactions which plagues the conventional position space non-compact formulation.
