A nonlocal classical perspective on quantum electrodynamics
The ideas behind the nonlocal classical statistical field theory model for the quantized Klein-Gordon field introduced in Morgan(2001, quantph/0106141) are extended to accommodate quantum electrodynamics. The anticommutation rules for the quantized Dirac spinor field are given a classical interpretation as a relativistically covariant modification of the minimal coupling interaction between the...
متن کاملCritical Charge in Quantum Electrodynamics
The critical nuclear charge Zcr and the critical distance Rcr in the system of two colliding heavy nuclei—they are defined as those at which the ground-state level of the electron spectrum descends to the boundary of the lower continuum, with the result that beyond them (that is, for Z > Zcr or R < Rcr) spontaneous positron production from a vacuum becomes possible—are important parameters in t...
متن کاملNonlocal Quantum Electrodynamics Admits a Finitely Induced Gauge Field Action
The Letter reconsiders a result obtained by Chrétien and Peierls in 1954 within nonlocal QED in 4D [Proc. Roy. Soc. London A 223, 468]. Starting from secondly quantized fermions subject to a nonlocal action with the kernel [i 6∂x a (x)− m b (x)] and gauge covariantly coupled to an external U(1) gauge field they found that for a = b the induced gauge field action cannot be made finite irrespecti...
متن کاملThe renormalization of charge and temporality in quantum electrodynamics
In this article it is intended a closer look at the renormalization procedure used in quantum electrodynamics to cope with the divergent integrals that appear in higher-order calculations within the theory. The main focus will be the charge renormalization that reveals, in a clearer way than the mass renormalization, structural limitations present in quantum electrodynamics that are even more a...
متن کاملEffective charge and fermion mass in strong coupling Quantum Electrodynamics
The effective charge and the dynamical electron mass are calculated non-perturbatively in strong coupling 3+1 dimensional quantum electrodynamics. Within the formalism of Dyson-Schwinger equations we solve the coupled equation for electron and photon propagator in Landau gauge. We restrict ourselves on the choice of Ball-Chiu vertex which is the minimal Anstaze for maintaing the gauge covarianc...
