Acceleration Radiation  

Bremsstrahlung > s.a. electromagnetism; particle effects; Stückelberg Mechanics.
* Idea: Radiation emitted by an accelerated electric charge.
* Fields: If one solves the wave equation in terms of advanced and retarded radiation fields, one can separate

AC:= \(1\over2\)(Areta + Aadva) ,      AR:= \(1\over2\)(AretaAadva) ;

The first one produces the Coulomb field, the second one is responsible for radiation reaction.
* Larmor equation: The rate of energy loss for an accelerated non-relativistic charged particle is dE/dt = 2q2(dv/dt)2/3c3.
* Examples: Synchrotron radiation.
* Issue in curved spacetime: When a charge is in free fall in a gravitational field, does it radiate or not? The answer is that a local detector, falling with it, would not detect radiation, but a distant one not falling with it would.
