The number of photons may change between inertial frames: a new "Unruh effect"

›
Let us work in semiclassical physics. Let us have a monochromatic laser beam which is reflected or is refracted by a small object (is scatte...

Classical bremsstrahlung

›
In our March 17, 2021 blog post we analyzed the Wikipedia formula for bremsstrahlung and the Gaunt factor. There we looked at processes wher...

Electron-electron (Møller) scattering bremsstrahlung cross section

›
We want to find out what is the structure of the inner electric field of the electron, that is, the structure for a radius less than the ele...

A real photon self-energy Feynman diagram

›
On May 12, 2021 we analyzed the electron self-energy and concluded self-energy has no effect on a free (real) electron. Let us consider a re...

The electron self-energy Feynman diagram

›
In our December 19, 2020 blog post we remarked that the Feynman diagram for the electron self-energy seems to break conservation of the spee...
