Description
There remains great interest in radiation reaction, both theoretically and experimentally, especially in the context of strong laser fields.
In this talk I will derive classical radiation reaction directly from QED. The treatment is fully quantum and and we make no approximation except the usual coupling expansion of QED.
We calculate the expectation value of the momentum and the position of an electron in QED. Taking the classical limit, hbar goes to zero, of these expectation values allows us to identify which of the many different classical equations proposed to describe radiation reaction are consistent with QED.
