Three-loop Euler-Heisenberg Lagrangian in 1+1 QED. Part I. Single fermion-loop part
Abstract We study the three-loop Euler-Heisenberg Lagrangian in spinor quantum electrodynamics in 1+1 dimensions. In this first part we calculate the one-fermion-loop contribution, applying both standard Feynman diagrams and the worldline formalism which leads to two different representations in ter...
