Résumé :

There are several quantum phenomena that can be described in a semiclassical approach, such as the Hawking effect, Schwinger pair production, and the Casimir effect. In this talk, we will focus on the role of resummations in this approach, which are necessary if one wants to access the nonperturbative regime. We will give a general overview of the results valid for quantum fields in curved spacetime and in electromagnetic backgrounds, including some recent novelties as well. Partly based on
