Talk:Quantum field theory

I think someone got the formula for the symmetric wave-function of a system of N bosons wrong. As it stands, it is not correctly normalized. What's really funny is that later on we have a (correct) example for a system of three particles which is not consistent with the general formula.

Well, I'd personally prefer a treatment of relativistic QFT expressed in the language of physics rather than mathematics. But I don't have time to work on the article right now. Oh well. -- CYD

I think something needs to be said about what is quantized. In QM we quantize the [x,p], but in QFT x,p are not really operators, instead we quantize [field,canonical momentum] which are operators. (and the field is not an operator in regular QM).

Also I think something needs to be said about the propigator greens function that really captures the heart of partical exchange and lots of new ideas. -- CHF

Recently, 145.254.153.97 changed a whole bunch of inline math from html tokens to <math> markup, whereas my understanding is that the preferred standard is to use html tokens for inline text, and the <math> tags for display mode formulas. Perhaps there is some reason that this article should break with this standard? -Lethe | Talk

It isn't really my area, but the schrodinger equation as quoted looks suspicious to me. Specifically, is it correct to have |p|^2 *\del ?

The Schrodinger equation is correct. p is the momentum operator. -- CYD
