Massless quantum electrodynamics with a critical point
Recently, it has been observed that a quantum field theory need not be Hermitian to have a real, positive spectrum. What seems to be required is symmetry under combined parity and time-reversal transformations. This idea is extended to massless electrodynamics, in which the photon couples to the axial-vector current with an imaginary coupling constant. The eigenvalue condition necessary for the...
متن کاملMassless and Massive Vector Goldstone Bosons in Nonlinear Quantum Electrodynamics
The spontaneous Lorentz invariance violation (SLIV) developing in QED type theories with the nonlinear four-vector field constraint A μ = M (where M is a proposed scale of the Lorentz violation) is considered in the case when the internal U(1) charge symmetry is also spontaneously broken. We show that such a SLIV pattern induces the genuine vector Goldstone boson which appears massless when the...
متن کاملMassless Classical Electrodynamics
In the direct action form of classical EM we give the equation of motion for a classical massless bare charge without self-interaction in the presence of an external field. That equation permits superluminal speeds and time-reversals, and so is a realization of the Stueckelberg-Feynman view of electrons and positrons as different segments of a single trajectory. We give a particular solution to...
متن کاملThe New Charged Massless States of Quantum Electrodynamics
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...
متن کاملInfrared Divergences in dS/CFT
dS/CFT gives a perturbatively gauge invariant definition of particle masses in de Sitter (dS) space. We show, in a toy model in which the graviton is replaced with a minimally coupled massless scalar field, that loop corrections to these masses are infrared (IR) divergent. We argue that this implies anomalous dependence of masses on the cosmological constant, in a true theory of quantum gravity...
