Landau-Khalatnikov-Fradkin Transformations in Reduced Quantum Electrodynamics: Perturbative and Nonperturbative Dynamics of the Fermion Propagator

Record completeness
Claims
Through numerical computation, we demonstrate that both the chiral fermion condensate and the fermion pole mass are gauge-invariant quantities.
The assumption that the Landau-Khalatnikov-Fradkin transformation derived in standard QED applies without modification to the reduced quantum electrodynamics case, including for the nonperturbative mass function.
LKF transformations give all-order gauge-transformed fermion propagators in RQED, with ξ=1/3 eliminating one-loop leading logs and numerical checks confirming gauge-invariant condensate and pole mass.
