Soft Expansion and Asymptotic Charges

In recent years there has been renewed interest in the infrared behavior of scattering amplitudes and its relation with asymptotic symmetries. I will first introduce the subject in the simple setting of dipole radiation.  I will then discuss higher order soft theorems in tree level QED and show how they can be interpreted in terms of asymptotic charges, generalizing previous results for the leading and subleading soft theorems.
