Wilson Coefficient for Vacuum Condensate of Photons from Electrodynamics Photon Propagator
نویسنده
چکیده
In the framework of the operator product expansion I provide a detailed evaluation of the contribution of the lowest photon condensate to the two-point photon Green function for four-dimensional spinor electrodynamics and three-dimensional scalar electrodynamics. Since the above mentioned condensate affects the part of the propagator contributing to physical amplitudes I suggest that this condensate could play a role in the non-perturbative dynamics of Abelian gauge field theories.

Quantum electrodynamics in the squeezed vacuum state: Feynman rules and corrections to the electron mass and anomalous magnetic moment
Due to the nonvanishing average photon population of the squeezed vacuum state, finite corrections to the scattering matrix are obtained. The lowest order contribution to the electron mass shift for a one mode squeezed vacuum state is given by δm(Ω, s)/m = α(2/π)(Ω/m) sinh(s), where Ω and s stand for the mode frequency and the squeeze parameter and α for the fine structure constant, respectivel...
متن کاملDressing the Quark with QCD Condensates
A condensate of p = 0 partons in the perturbative vacuum gives rise to a term ∝ δ(p) in the free PQCD propagators. The leading condensate contribution to the quark propagator can be exactly summed since there is a factor δ(p) associated to each loop. We calculate the dressed quark propagator in the presence of either a gluon or a quark condensate, for a number of colors N → ∞. The dressed quark...

The behavior of photons in the presence of Lorentz and CPT violation is studied. Allowing for operators of arbitrary mass dimension, we classify all gauge-invariant Lorentzand CPT-violating terms in the quadratic Lagrange density associated with the effective photon propagator. The covariant dispersion relation is obtained, and conditions for birefringence are discussed. We provide a complete c...
متن کاملJa n 20 02 Propagator approach to cavity QED dressed atom - photon scattering
We present a propagator formalism to investigate the scattering of photons by a cavity QED system that consists of a single two-level atom dressed by a leaky optical cavity field. We establish a diagrammatic method to construct the propagator analytically. This allows us to determine the quantum state of the scattered photons for an arbitrary incident photon packet. As an application, we explic...
