Reduction of order, resummation and radiation reaction
Robin Ekman, Tom Heinzl, Anton Ilderton
The Landau-Lifshitz equation is the first in an infinite series of approximations to the Lorentz-Abraham-Dirac equation obtained from `reduction of order'. We show that this series…
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…
Two toy models for the motion of a leaky tank car
Robin Ekman
I present two toy models for the motion of a tank car as fluid drains out of an off-center opening, based on replacing the fluid with particles. No knowledge beyond simple Lagrangi…
Relativistic kinetic theory for spin-1/2 particles: Conservation laws, thermodynamics, and linear waves
R. Ekman, H. Al-Naseri, J. Zamanian +1
We study a recently derived fully relativistic kinetic model for spin-1/2 particles. Firstly, the full set of conservation laws for energy, momentum and angular momentum are given,…
