The New Charged Massless States of Quantum Electrodynamics
نویسنده
چکیده
Quantum Electrodynamics can be formulated as the theory of an antisymmetric tensor gauge field. In this formulation the topologi-cal current of this field appears as an additional source for the electromagnetic field.The topological charge therefore acts physically as an electric charge. The topologically nontrivial, electrically charged, sector contains massless states orthogonal to the vacuum which are created by a gauge invariant local operator and can be interpreted as coherent states of photons.

Are There Topologically Charged States Associated with Quantum Electrodynamics ?
We present a formulation of Quantum Electrodynamics in terms of an antisymmetric tensor gauge field. In this formulation the topo-logical current of this field appears as a source for the electromagnetic field and the topological charge therefore acts physically as an electric charge. The charged states of QED lie in the sector where the topological charge is identical to the matter charge. The...
متن کاملAn Analysis of Circulation of Decentralized Digital Money in Quantum Electrodynamics Space: the Econphysics Approach
The study aimed at showing how to create and release cryptocurrency, based on which one can introduce a new generation of this money that can continue its life in the quantum computers space and study whether cryptocurrency could be controlled or the rules should be rewritten in line with new technology. Regarding this, we showed the evolution of money and its uses in economic relations. Accord...
متن کاملFirst quantized electron and photon model of QED and radiative processes
In this study we combine the classical models of the massive and massless spinning particles, derive the current-current interaction Lagrangian of the particles from the gauge transformations of the classical spinors, and discuss radiative processes in electrodynamics by using the solutions of the Dirac equation and the quantum wave equations of the photon. The longitudinal polarized photon sta...
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...
