Hi,
I have a question that how to interpret the field function Φ in Quantum Field Theory.
As I can see, it is an operator through second quantization and the co-ordinate representation no long exist after second quantization.
So we cannot regard it as wave function any more.
Could...
Thank you very much.
I am thinking about my future research interest: mathematical relativity, topological QFT, conformal field theory, and maybe statistical physics...
Personally, I am interested in Topological Quantum Field Theory. And now I am battling against Quantum Field Theory. I am not sure how much Quantum Field Theory is needed to do Topological Quantum Field Theory. And I am not sure what should be the mathematical pre-requisites of Topological...
One of my questions has been resolved.
Spin is considered in angular momentum term, so it should have spacetime variation. Thus, it is in exterior symmetry.
Hi,
I have already been familiar with that exterior symmetry is the spacetime symmetry. Such kind of symmetry has been depicted by Poincare' group.
Then I am still find the concept internal space/internal symmetry ambiguous.
And I cannot understand why put Spin in exterior symmetry not...
What is "Little Group"?
In my Quantum Field Theory class, I too often meet with the term "Little Group".
Unfortunately, I cannot find a good description of Little Group until now. I just know it is a subgroup of Lorentz Group.
Can anyone have any brief description of this concept? Or any...
A serious student in theoretical physics program should look into John Baez's reading list.

Also anyone could find a lovely tutorial material on General Relativity on John Baez's website.

Thank you very much. I should say sorry.
But I think your recommendation is oriented to experimentalists or applied physicists.
I think you are in a wrong drama. We can always find a streamlined structure of modern theory. And we can always find short-cut into our cutting edge research.
Sometimes those stuffs are only for historical interest. You are wasting your time in advertising those books.
For those want to...
I am so happy you want to enrich your physics background. You may benefit from this attempt.
Why not look into John Baez's Reading List.
