The Dirac Field and the Electromagnetic Field in Interaction. Perturbation Theory,ion, we will continue to use the Dirac equation (16.1), except that ..(.) is now the operator of the quantized electromagnetic field, and not an external field. In certain problems it is necessary to use not only the quantized field, but also to add an external field. Then ..(.) becomes the sum of bVisual-Acuity 发表于 2025-3-23 21:00:04
Elementary Applications,(see also footnotes 2, 3) and also because the details belong in Vol. XXXI of this handbook,. we shall not attempt to be complete. The following calculations are to be considered only as examples of results which are obtained rather easily with modern quantum electrodynamics, although they were usua贵族 发表于 2025-3-23 22:51:22
General Theory of Renormalization,tion, may be interpreted physically by means of the renormalization of the charge and mass of the electron and so may be eliminated. The remaining finite terms can be compared with experimental measurements. The calculated and measured values show remarkably good agreement. In a few cases the resultobsolete 发表于 2025-3-24 02:23:59
Gunnar Källénl repayment. Rather than bring the dead back to life, or even restore them to wholeness, both volumes depict scenes of displacement, translation, and transposition that emphasize the poem’s (figurative) aliveness while paradoxically embracing indebtedness.一个姐姐 发表于 2025-3-24 06:33:38
