Description

This lecture covers the concept of Fourier modes in Quantum Field Theory, focusing on the use of variables that transform well under translations. It explains the importance of Fourier modes in systems at finite volume, discussing the invariance under translations and the creation and destruction operators. The lecture also delves into the normalization of states in a relativistic context.
