Lecture 4 : Introduction to the quantisation of fields in curved space-time and to the in-in formalism
Diego Chialva (UMONS, Belgique)

Résumé :
This short series of lectures will cover essentially four topics: quantization of fields in curved space-time, De Sitter and other examples of time-evolving backgrounds, observables and in-in formalism and, time allowing, elements of effective theory. The emphasis of the course will be on the concepts. Examples and calculations will be adapted pedagogically and simplified, but they will still suffice to convey relevant concepts like the nature of vacuum and "particles" on curved background, or the theory of interactions on time-evolving backgrounds. This will provide the audience with a sufficiently solid introduction to quantum field theory on curved background, and prepare for more advanced aspects.
