Stability of QED
where D is the free photon propagator in some fixed gauge. Naively, integration over the fermion fields produces the ratio of determinants detð6 P e 6 AþmÞ= detð6 PþmÞ, which is not well defined; detren makes sense of this ratio. It is gauge invariant and depends only on the field strength F and invariants formed from it. We have chosen to introduce this paper with an abrupt intrusion of defini...
متن کاملQuantum Stability of the Phase Transition in Rigid QED
Rigid QED is a renormalizable generalization of Feynman’s space-time action characterized by the addition of the curvature of the world line (rigidity). We have recently shown that a phase transition occurs in the leading approximation of the large N limit. The disordered phase essentially coincides with ordinary QED, while the ordered phase is a new theory. We have further shown that both phas...
متن کاملHigher - Order Qed Effects and Nonlinear Qed
After a brief review of higher-order QED effects, a survey is made of novel aspects of QED with emphasis on recent experimental results in strong-field QED: nonlinear Compton scattering and multiphoton pair creation by light. 1 Higher-Order QED Effects Quantum Electrodynamics (QED) describes the interactions between charged particles that are mediated by quanta (photons) of the electromagnetic ...
متن کاملRenormalization flow of QED.
We investigate textbook QED in the framework of the exact renormalization group. In the strong-coupling region, we study the influence of fluctuation-induced photonic and fermionic self-interactions on the nonperturbative running of the gauge coupling. Our findings confirm the triviality hypothesis of complete charge screening if the ultraviolet cutoff is sent to infinity. Though the Landau pol...
