Advanced quantum field theory, Lecture 1

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 1 I discuss path integrals.

Thank you so much Prof. Tobias Osborne. I have been searching for a good set of lectures on QFT for a while, and here I am finally discovered what I have been looking for. And thank you Alexander St. John for spending your time transcribing the lectures, it helped me a lot.

Greatly appreciated your remarks at the end of the video.

Dear Prof Osborne,
Are there written notes for these lectures?
Thank you.

thank you very much. You are our professor indeed!!!

Why is the position eigenbasis not really a proper basis at all?

Tobias, a general question about how to engage in independent study of physics (my background is that I have BSc in physics but have no formal training beyond that) : do you think I can safely assume that any book published by a reputable company such as Springer, CRC or any of the ubiquitous University Presses will be providing accurate and correct contect? my main concern is that I might pick up a book that will espouse incorrect physics and/or offer unhelpful ways of understanding or interpreting a phenomenon

Hi Dr. Osborne,

I am a particle physics graduate student organizing a study group with some fellow students for advanced QFT. We would like to use your lectures, and I was wondering if there is there any way that I can access the problem sets that you assigned for this class?

Thank you,
Mitch

Dear Prof Osborne,

Is there any way to get hold of the corresponding assignments following the your courses on Advanced Quantum Mechanics, Quantum Field Theory and Advanced Quantum Field Theory? It would be of great help along with your mode of instruction that we can obtain from your lecture videos. Please keep up the great work. And can't wait for the lectures on symplectic geometry and classical mechanics.

awsome! hope that u will upload the whole modul <3

String theory And Quantum make videos of these

I'm wondering about the rigorous results alluded to in the video. For one, does the statement "you can construct the path integral rigorously and use it to quantize classical systems only if you know the answer already" point to the rigorous construction of path integral measures in certain special cases (even for interacting quantum fields)? Are there and good materials for the mathematical background of this? Also I can't find any decent overview of the Duistermaat–Heckman stuff. Does someone know a good reference? (I assume that's very much related for the classical mechanics course going on now)

[ArponPaul]

Where can I find the problem set of the course? Thanks in advance!

Hi, I wonder whether there are the lecture notes of the video?

[acreed]

ok then Classical okkk and thx for ur support
