On-shell effective field theory and quantum transport for hard photons
Marc Comadran, Cristina Manuel
We develop an effective field theory for the description of high energetic or hard photons, the on-shell effective theory (OSEFT). The OSEFT describes the so called eikonal or semi…

Photon quantum kinetic equations and collective modes in an axion background
Marc Comadran, Cristina Manuel
We develop a quantum kinetic theory for photons in the presence of an axion background and in the collisioness limit. In deriving the classical regime of our quantum kinetic equati…
