High-intensity scaling in UV-modified QED
Robin Ekman, Tom Heinzl, Anton Ilderton
QED perturbation theory in a background field has been conjectured to break down for sufficiently high field intensity. The high-intensity behavior of a field theory is however int…

Kinetic theory for spin-1/2 particles in ultra-strong magnetic fields
Haidar Al-Naseri, Jens Zamanian, Robin Ekman +1
When the Zeeman energy approaches the characteristic kinetic energy of electrons, Landau quantization becomes important. In the vicinity of magnetars, the Zeeman energy can even be…

Back-reaction in strong field QED: a toy model
Robin Ekman, Anton Ilderton
As a toy model for QED in strong background fields, we consider the impact of back-reaction and loop effects on scattering processes in quantum optics. We show that neglecting back…
