Advanced quantum field theory, Lecture 16

This summer semester (2017) I am giving a course on advanced quantum field theory. This course is intended for theorists with familiarity with advanced quantum mechanics, statistical physics, and quantum field theory (for a good foundation see my videos on advanced QM and QFT). The main objective is discuss the building blocks of the standard model, including, Yang-Mills theory and symmetry breaking.

Here in Lecture 16 I discuss spontaneous symmetry breaking and Goldstone's theorem.

Thanks for this fantastic lecture! You put much emphasis on the essential physics and do not get lost in maths. Really like how the models are explored.

Excellent lecture series... It will be nice if more advanced topics are also uploaded... Thanks

there is a thing i cannot understand about the proof of Goldstone's theorem, the theorem says that for every broken symmetry there is a massless boson particle but we seem to prove that for every continuous symmetry there is a massless boson particle. Are those 2 claims linked in some way?
