@A. Neumaier , Thank you for your answer. Your answer to my first two questions makes sense. but in answer to my third question, you said: I think you misinterpreted what I was asking. I meant to ask why does that proportionality imply the energy density relation? I.e., $$ e^{\sum V_i}\propto...

I am reading Peskin-Schroeder's QFT text, and there on pg. 98 Equation (4.56) they derive the expression for the vacuum energy density (relative to the zero of energy set by ##H_0|0\rangle = 0##): $$ \frac{E_0}{\rm{Volume}} = \frac{i\,\sum\text{(all disconnected pieces)}}{(2\pi)^4\,\delta^4(0)}\...

My current academic training has been more focused on the theoretical math side of things. This is mainly because my undergrad institution didn't have a strong theoretical physics program and I wasn't really into the experimental side of things. However, I had taken all the "theory" based...

For the moment I'm just an independent research. I said beginning grad just to give an idea of my academic preparation so far. So to answer your question, no, I won't have an advisor. That's one of the big reasons of posting here to see if someone could suggest looking into something.

I am highly interested in Topological Quantum Field Theory (TQFT) and am currently planning on doing a project on this topic this year. Some of my relevant background: Algebra (Groups, Rings, Fields, basics of Categories and Modules), Topology (Munkres), Smooth Manifolds (John Lee's book, first...
