Everlasting interaction: polarization summation without a Landau pole
Stefan Evans, Johann Rafelski
We propose an external field approach to evaluating effective action allowing the interaction to act everywhere at all times (everlasting). Requiring that the asymptotic gauge fiel…

Comment on "All-Loop Result for the Strong Magnetic Field Limit of the Heisenberg-Euler Effective Lagrangian"
Stefan Evans, Johann Rafelski
We offer a 2nd look at the recently claimed improvement of Euler-Heisenberg-Schwinger (EHS) action [PRL \textbf{122} (2019) no.21, 211602 and post-publication correction]: We demon…
