Qed 1+1 by Dirac Quantization
نویسنده
چکیده
Dirac quantization of electrodynamics on a two-dimensional cylindrical space-time, is considered in an explicit loop and functional representation. Expressions for a sufficient number of physical states are found, so that an inner product can be derived on the space of physical states. The relevant states are found to be a superposition of two disjoint sectors. The ground state is investigated and the investigations are met with partial success. Email address: [email protected]

We enlarge the local gauge invariance of QED from U(1)A to U(1)A × U(1)Θ by introducing another unphysical pure gauge field Θ with an independent, unphysical gauge coupling ẽ . This pure gauge field can be gauge-transformed away and the resulting theory is identical to standard QED. We then re-examine the Dirac quantization condition (DQC) for point monopoles and find that two essentially diffe...
متن کاملInconsistency of QED in the Presence of Dirac Monopoles II
We enlarge the local gauge invariance of QED from U(1)A to U(1)A U(1) by introducing another unphysical pure gauge eld with an independent, unphysical gauge coupling ~ e . This pure gauge eld can be gauge-transformed away and the resulting theory is identical to standard QED. We then re-examine the Dirac quantization condition (DQC) for point monopoles and nd that two essentially di erent DQCs ...
متن کاملInconsistency of QED in the Presence of Dirac Monopoles I . 1
A precise formulation of U(1) local gauge invariance in QED is presented, which clearly shows that the gauge coupling associated with the unphysical longitudinal photon eld is non-observable and actually has an arbitrary value. We then re-examine the Dirac quantization condition (DQC) and nd that its derivation involves solely the unphysical longitudinal coupling. Hence an inconsistency inevita...
متن کاملMagnetic Monopole is Photon
It is shown that a photon with a specific frequency can be identified with the Dirac magnetic monopole. When a Dirac-Wilson line forms a Dirac-Wilson loop, it is a photon. This loop model of photon is exactly solvable. From the winding numbers of this loop-form of photon, we derive the quantization properties of energy and electric charge. A new QED theory is presented that is free of ultraviol...
متن کاملIrreducible representations of the CPT groups in QED
We construct the inequivalent irreducible representations (IIR’s) of theCPT groups of the Dirac field operator ψ̂ and the electromagnetic quantum potential Âμ. The results are valid both for free and interacting (QED) fields. Also, and for the sake of completeness, we construct the IIR’s of the CPT group of the Dirac equation.
