Trento talk

My student David Reeb will be attending this meeting at ECT Trento next week:

Sign Problems and Complex Actions

workshop at ECT* Trento

Monday March 2 - Friday March 6 2009

organizers: Gert Aarts (Swansea University) & Shailesh Chandrasekharan (Duke University)

I would really have liked to go but my wife is giving a talk at Emory at the same time so I am stuck at home watching the twins. No Alps for me :-/

Here are the excellent slides for David's talk. The first section is a nice introduction to Monte Carlo methods in quantum field theory, which he made for a local seminar here in the ITS (for non-experts).

I'm going to ask a really dumb question. What does F^{a}_{\mu \nu} actually LOOK like? [Latex mileage may vary; I typically post as David]

Steve Hsu said...

If you are familiar with F_mn for the electromagnetic field, just imagine another "internal", "color" space along which the fields align. So you have different "kinds" of electric and magnetic field.

Hope that helps!

I am familiar with F_mn. I guess what I'm getting at is that I've never really gotten how you calculate [and calculate with] a tensor that has both co- and contravariant components.

So I guess I should add that that this would be more apparent if I actually read a book on QCD. Any recommendations?

Steve Hsu said...

Actually, nothing good pops into my head for non-experts. For someone who already knows quantum field theory I can think of several options.

Perhaps Kerson Huang's book Quarks and Leptons?
