Quantum Electrodynamics without Infinities
نویسنده
چکیده
The use of a fermion Green’s function involving no delta functions is demonstrated. This Green’s function is employed to compute the first order contribution to the vacuum polarization of the hydrogen Lamb shift. No infinities appear so that regularization is unnecessary. The numerical value of this contribution to the vacuum polarization is shown to be identical to the value obtained by regularization.

Photons and temporality in quantum electrodynamics
The lowest order processes described within quantum electrodynamics are free from the problem with infinities in the theory, and can be dealt with disregarding the need for charge and mass renormalization. This might indicate that the space-time description of these processes is not only consistent but also could give a privileged insight to the functioning of models provided by the theory. The...
متن کاملDynamical evolution of nonclassical properties in cavity quantum electrodynamics with a single trapped ion
In this paper, by considering a system consisting of a single two-level trapped ion interacting with a single-mode quantized radiation field inside a lossless cavity, the temporal evolution of the ionic and the cavity-field quantum statistical properties including photon-counting statistics, quantum fluctuations of the field quadratures and quantum fluctuations of the ionic dipole variables are...
متن کاملCalculation of Kolmogorov Entropy in Cavity Quantum Electrodynamics
In this paper Kolomogorov entropy of a simulated cavity quantum electrodynamics in a multi-partite system consisting of eight quantum dots in interaction with one cavity mode has been estimated. It has been shown that the Kolmogorov Entropy monotonically increases with the increasing coupling strength, which is a sufficient condition for chaotic behavior under ultrastrong coupling regime. The a...
متن کاملInterrelations between Mathematics and Experiment in the Present Structure of Quantum Electrodynamics
The electromagnetic interaction of the hydrogen atom is used as an experimental device and the data prove that bound fields and radiation fields are different physical objects. A further analysis proves that there is no direct interaction between radiation fields and there is no self-interaction of fields of an elementary pointlike charge. Therefore, bound fields and radiation fields should be ...
