Advanced quantum field theory, Lecture 2

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 2 I discuss gaussian path integrals.

Thanks for your generous sharing. Are you preparing to have a set of lectures on condensed matter or standard model ?

It may be too late, I'm wondering why you are using four vector notation (nabla) when discretising 39:11. Only the space are now discretized, am I right? (non-relativistic)
Thanks for giving me this nice lecture!

i know this is too late but i don't understand how epsilon^-3 came about and why it shouldn't be epsilon^-6

Dear Tobias,


how about a class on General Relativity :))
Greetings

should there be two factors of 1/c(epsilon), and 19:04 ? Also, around that time we drop the superscript j's and the sum over j in the exponent. Are we assuming a one dimensional system?

This reminds me of The Far Side cartoon, with a blackboard full of gibberish and a small box that reads [and here a miracle happens].
