Interrelations between Mathematics and Experiment in the Present Structure of Quantum Electrodynamics  [PDF]
Eliahu Comay
Open Access Library Journal (OALib Journal) , 2015, DOI: 10.4236/oalib.1102211
Abstract: 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 treated differently and radiation fields emitted from two different sources should be treated separately. The fields term of the electromagnetic Lagrangian density Lem=-Fuv Fuv/16π; does not abide by these properties of electromagnetic fields, because Fuv is the sum of all kinds of fields. This is the underlying reason for the infinities of quantum electrodynamics and for the erroneous energy-momentum tensor which is obtained from an analysis of Lem.
Elementary Errors in Contemporary Theoretical Physics  [PDF]
Eliahu Comay
Open Access Library Journal (OALib Journal) , 2016, DOI: 10.4236/oalib.1102585
Abstract:
The paper discusses two cases showing crucial effects of error correction. It proves that contrary to the common belief, the electronic state of atoms having more than one electron has a multiconfiguration structure and that the central field approximation provides an inadequate description of the wave function. Fundamental isospin properties prove that baryonic quarks (like those of the ) can be regarded as ordinary Dirac particles. Theoretical consequences of these issues are discussed.
A Theory of Weak Interaction Dynamics  [PDF]
Eliahu Comay
Open Access Library Journal (OALib Journal) , 2016, DOI: 10.4236/oalib.1103264
Abstract:
Problems with the electroweak theory indicate the need for a consistent weak interactions theory. The analysis presented in this work is restricted to the relatively simple case of elastic scattering of a neutrino on a Dirac particle. The theory presented herein assumes that the neutrino is a massive particle. Furthermore, the dimension [L2] of the Fermi constant Gas well as its universal property are used as elements of the theory. On this basis, it is assumed that weak interactions are a dipole-dipole interaction mediated by a weak field. An interaction term that represents weak interactions is added to the Dirac Lagrangian density. The identity is used in an analysis which proves that the interaction violates parity because it consists of two terms-a vector and an axial vector. This outcome is in accordance with the experimentally confirmed V-A property of weak interactions
Further Aspects of Weak Interaction Dynamics  [PDF]
Eliahu Comay
Open Access Library Journal (OALib Journal) , 2017, DOI: 10.4236/oalib.1103397
Abstract:
This work discusses properties of a recently published weak interactions theory which is derived from a Lagrangian density Lw. This theory depends on the experimentally confirmed massive neutrino. The interaction which is carried by an appropriate mediating field is consistent with the Fermi coupling constant of weak interactions GF. Its results prove the existence of a vector term V and an axial vector term A in a description of weak interactions processes and of their associated parity nonconservation. An analysis of the weak interactions Lagrangian density Lw shows similarity and differences between the theoretical structure of electrodynamics and that of weak interactions.
Gauge Contradictions in the QED Lagrangian Density  [PDF]
Eliahu Comay
Open Access Library Journal (OALib Journal) , 2017, DOI: 10.4236/oalib.1103596
Abstract:
This work distinguishes between classical electrodynamics where Maxwell equations and the Lorentz force are used as the theory’s cornerstone (MLE) and electrodynamic theories that are derived from the variational principle (VE). The paper explains the significance of this distinction. Mathematical elements of gauge transformations are examined within the realm of these theories. The analysis proves that MLE is a gauge invariant theory whereas errors arise from the introduction of gauge transformations into VE. The paper explains why MLE evades the contradictions of VE.
On the Crucial Role of the Variational Principle in Quantum Theories  [PDF]
Eliahu Comay
Journal of Applied Mathematics and Physics (JAMP) , 2017, DOI: 10.4236/jamp.2017.511171
Abstract: The paper shows that the variational principle serves as an element of the mathematical structure of a quantum theory. The experimentally confirmed properties of the corpuscular-wave duality of a quantum particle are elements of the analysis. A Lagrangian density that yields the equations of motion of a given quantum theory of a massive particle is analyzed. It is proved that if this Lagrangian density is a Lorentz scalar whose dimension is \"\"?then the associated action consistently defines the required phase of the quantum particle. The \"\" dimension of this Lagrangian density proves that also the quantum function \"\"?has dimension. This result provides new criteria for the acceptability of quantum theories. An examination of the first order Dirac equation demonstrates that it satisfies the new criteria whereas the second order Klein-Gordon equation fails to do that.
On the Significance of Standard Model Errors  [PDF]
Eliahu Comay
Open Access Library Journal (OALib Journal) , 2017, DOI: 10.4236/oalib.1104164
Abstract:
The paper discusses the existence of errors in the Standard Model. An adequate amount of examples and references support the arguments. The errors belong to the electromagnetic, strong and weak interactions sectors of the Standard Model. It turns out that this state of affairs is far from being well-known and too many people unjustifiably glorify the Standard Model as an excellent theory. It is explained why a reexamination of the Standard Model can only improve the status of physics.
A Consistent Construction of the Electromagnetic Energy-Momentum Tensor  [PDF]
Eliahu Comay
Open Access Library Journal (OALib Journal) , 2018, DOI: 10.4236/oalib.1104354
Abstract:
This work discusses the problem of the apparently non-symmetric form of the electromagnetic fields’ energy-momentum tensor, which is obtained from the variational principle. The analysis treats differently radiation fields and bound fields. This distinction has a solid experimental basis where the hydrogen atom proves that radiation fields and bound fields have a different spin and a different parity. A direct calculation proves that in the case of radiation fields, the variational principle yields the well known symmetric energy momentum tensor and the problem does not exist.
Inherent Differences between Bound and Radiation Fields  [PDF]
Eliahu Comay
Open Access Library Journal (OALib Journal) , 2018, DOI: 10.4236/oalib.1104517
Abstract:
The purpose of the paper is to use fundamental theoretical and experimental elements of electrodynamics for deriving properties of radiation fields and of bound fields. A wide variety of examples prove that radiation fields and bound fields do not represent the same physical object. This conclusion is new. Some examples belong to the classical domain and others belong to the quantum domain. Consequences of this outcome affect several physical issues. In particular, these fields should be treated separately. For this reason, changes must be introduced to the present form of the fields’ Lagrangian density of quantum electrodynamics, where the fields tensor Fuv is a sum of bound and radiation fields. Since the Lagrangian density is a key element of the theory, its revision may entail changes of other specific issues. The recent failure of quantum electrodynamics to explain the electron and the muon data of the proton charge radius supports this conclusion.
A Holevo-Type Bound for a Hilbert Schmidt Distance Measure  [PDF]
Boaz Tamir, Eliahu Cohen
Journal of Quantum Information Science (JQIS) , 2015, DOI: 10.4236/jqis.2015.54015
Abstract: We prove a new version of the Holevo bound employing the Hilbert-Schmidt norm instead of the Kullback-Leibler divergence. Suppose Alice is sending classical information to Bob by using a quantum channel while Bob is performing some projective measurements. We bound the classical mutual information in terms of the Hilbert-Schmidt norm by its quantum Hilbert-Schmidt counterpart. This constitutes a Holevo-type upper bound on the classical information transmission rate via a quantum channel. The resulting inequality is rather natural and intuitive relating classical and quantum expressions using the same measure.
