LBL-35971 Quantum Electrodynamics at Large Distances I: Extracting the Correspondence-Principle Part. ∗
The correspondence principle is important in quantum theory on both the fundamental and practical levels: it is needed to connect theory to experiment, and for calculations in the technologically important domain lying between the atomic and classical regimes. Moreover, a correspondenceprinciple part of the S-matrix is normally separated out in quantum electrodynamics in order to obtain a remai...
متن کاملQuantum Electrodynamics at Extremely Small Distances
The asymptotics of the Gell-Mann – Low function in QED can be determined exactly, β(g) = g at g → ∞, where g = e is the running fine structure constant. It solves the problem of pure QED at small distances L and gives the behavior g ∼ L. According to Landau, Abrikosov, Khalatnikov [1], relation of the bare charge e0 with the observable charge e in quantum electrodynamics (QED) is given by expre...
متن کاملF eb 1 99 5 February 1 , 2008 LBL - 35973 Quantum Electrodynamics at Large Distances III : Verification of Pole Factorization and the Correspondence Principle
In two companion papers it was shown how to separate out from a scattering function in quantum electrodynamics a distinguished part that meets the correspondence-principle and pole-factorization requirements. The integrals that define the terms of the remainder are here shown to have singularities on the pertinent Landau singularity surface that are weaker than those of the distinguished part. ...
متن کاملQuantum electrodynamics at large distances. II. Nature of the dominant singularities.
Accurate calculations of macroscopic and mesoscopic properties in quantum electrodynamics require careful treatment of infrared divergences: standard treatments introduce spurious large-distances effects. A method for computing these properties was developed in a companion paper. That method depends upon a result obtained here about the nature of the singularities that produce the dominant larg...
متن کاملCorrespondence Principle in Quantum Gravity
The problem of consistent formulation of the correspondence principle in quantum gravity is considered. The usual approach based on the use of the two-particle scattering amplitudes is shown to be in disagreement with the classical result of General Relativity given by the Schwarzschild solution. It is shown also that this approach fails to describe whatever non-Newtonian interactions of macros...
