Fermion Propagator in Quenched QED3 in the Light of the Landau-Khalatnikov-Fradkin Tranformation
We study the gauge dependence of the fermion propagator in quenched QED3, with and without dynamical symmetry breaking, in the light of its Landau-Khalatnikov-Fradkin transformation (LKFT). In the former case, starting with the massive bare propagator in the Landau gauge, we obtain non perturbative propagator in an arbitrary covariant gauge. Carrying out a perturbative expansion of this result,...
متن کاملInverse Landau-Khalatnikov Transformation and Infrared Critical Exponents of (2+1)-dimensional Quantum Electrodynamics
By applying an inverse Landau-Khalatnikov transformation, connecting (resummed) SchwingerDyson treatments in non-local and Landau gauges of QED3, we derive the infrared behaviour of the wave-function renormalization in the Landau gauge, and the associated critical exponents in the normal phase of the theory (no mass generation). The result agrees with the one conjectured in earlier treatments. ...
متن کاملGauge Covariance and the Chiral Condenate in QED3
The ambiguities associated with the lack of gauge invariance in the non-perturbative truncations of Schwinger-Dyson equations (SDEs) are a challenging problem which has not yet been resolved in a decisive fashion. Pursuing this aim, we study dynamical chiral symmetry breaking in quantum electrodynamics in three space-time dimensions (QED3). We investigate the gauge dependence of the chiral cond...
متن کاملEffective charge and fermion mass in strong coupling Quantum Electrodynamics
The effective charge and the dynamical electron mass are calculated non-perturbatively in strong coupling 3+1 dimensional quantum electrodynamics. Within the formalism of Dyson-Schwinger equations we solve the coupled equation for electron and photon propagator in Landau gauge. We restrict ourselves on the choice of Ball-Chiu vertex which is the minimal Anstaze for maintaing the gauge covarianc...
متن کاملTruncated Schwinger-Dyson equations and gauge covariance in QED3
We study the Landau-Khalatnikov-Fradkin transformations (LKFT) in momentum space for the dynamically generated mass function in QED3. Starting from the Landau gauge results in the rainbow approximation, we construct solutions in other covariant gauges. We confirm that the chiral condensate is gauge invariant as the structure of the LKFT predicts. We also check that the gauge dependence of the c...
