    How to interpret the field function Φ in QFT?

    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...

    What would be the pre-requisites to learn Topological Quantum Field Theory?

    Thank you very much. I am thinking about my future research interest: mathematical relativity, topological QFT, conformal field theory, and maybe statistical physics...

    What would be the pre-requisites to learn Topological Quantum Field Theory?

    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...

    What is internal space/internal symmetry?

    How about SU(3), SU(5)? Are they all internal symmetry?

    What is internal space/internal symmetry?

    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.

    What is internal space/internal 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 ?

    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...

    List: texts/ideas for BS math/phy to grad school

    A serious student in theoretical physics program should look into John Baez's reading list. http://math.ucr.edu/home/baez/books.html Also anyone could find a lovely tutorial material on General Relativity on John Baez's website.

    Please recommend differential geometry books

    Why not pay attention to John Baez's Recommendation? http://math.ucr.edu/home/baez/books.html

    A syllabus of books/literature from calculus to group theory to QFTs

    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 think you are trying to transform a physics Genius to a Nerd. Ordinarily, a physicist do not need that much math at beginning. Learn math in real physical application.

    Is there any good reference on Riemann Surface and Riemann Theta Function?

    Hi, Currently, I need to read some reference about Integrable System, but I am stuck in Riemann Surface, genus, divisors, and Riemann Theta Functions. This makes me anxious. Is there introduction or pedagogical reference on this topic? I think I can spend some time read it during winter...

    What is the Genus of Riemann Surface?

    I learnt something about genus in Topology. The concept Genus in Topology is intuitive and lucid. Now I am confronted with the Genus in Riemann Surface. I do not know what is Genus on Riemann Surface. Is it relevant to "singularity"? Anyone can help me make it a bit clear? Thanks.

    Tensors, metrics, differential geometry, and all that

    My favorite GR introductory books are Wolfgang Rindler's "Relativity: Special, General and Comological" and Ray de'Inverno's "Introducing Einstein's Relativity". Ray de'Inverno's book provides you lots of exercises on tensor calculus. Most of his exercises are straightforward, easy-to-do, but...

    Are there any book can serve as the companion book to Peskin's QFT?

    Thank you very much, good man... Zinn-Justin's book, I think, should be a marvelous work. Very decent and elegant. But I think it is good for me only if I use it as my second time learning material. Actually I have not seriously learnt QFT before, so what I need currently is a book at...

    Are there any book can serve as the companion book to Peskin's QFT?

    Oh, I made a mistake... "Gauge Theories in Particle Physics" has been updated to 3rd edition and the authors have changed into "I.J.R. Aitchison, A.J.G. Hey"

    Are there any book can serve as the companion book to Peskin's QFT?

    Hi, guys. I will start learning Peskin's QFT from the coming fall semester. I plan to spend 2 years for studying in order to strike a thorough understanding of QFT. Peskin's QFT book in general is a good one, but it focus on calculation techniques; thus, I think I need a companion book which...

    Is it easy for international students in U.S. find job in college or in university?

    I just wonder the way you talk is so aggressive. You try to channel or persuasive people to believe as you expect. The way you express your opinions is filled with black-white thinking or trying to put someone else in sort of "dilemma" as you designed. It is the common sense that causal...

    Is it easy for international students in U.S. find job in college or in university?

    I think my best policy is to discuss this with Chinese Professors in my department. I can share their experience on how to survive and success in U.S academia. And they could be my "primary" network in U.S.. Some note-posters here still worry about their jobs.

    Unfortunately.... Coming back to China would be my last choice and worst choice. My parents still expect that in future I can find some way to get them out of China.P.R... My mother is now working (ready to retire) in an university in China, she is quite discontent with the whole system. My...

    Is it easy for international students in U.S. find job in college or in university?

    If I tell you it ranking between 40 to 50, the info does any help to your asspt? All in all, it is quite likely that I might go to Germany in future for post doctor degree. Perhaps I should work hard enough to be the "strongest" then I can "survive"... I totally have no idea.
