How to compute the path integral in Chen-Simons theory?(the one Witten used to explain Jone polynomial)? Is there any measure in there? Thanks!

What's the relation of it with Wightman axioms ans etc.? Thanks! Or which one is the one we prefer?

I'm reading an 'armchair physics' book (A User's Guide to the Universe), and find it fascinating, but am having trouble understanding something that seems pretty fundamental. Conc …

Can someone point me towards (or just give) a clear mathematical explanation of what a spinor is and how one computes with them? I'm reading some QM textbooks that use them to des …

To date, what is the most mathematically precise formulation of the AdS/CFT correspondence, and what are the most robust tests of the conjecture?

Firstly is there an intuitive argument to see why the chemical potential of a system of free bosons should be negative and why for free fermions at high temperatures the chemical p …

I would like to open a question where you can put your favourite books into the answer. Please provide the required level e.g. starter, studied and professional

Does a position operator acting on a wavefunction give a position eignenfunction?

When a body moves aren't we supposed to say that each particles on the body moves with same velocity and so the de-broglie wave corresponding to each particle must have the same ve …

Do we know the answer s to some or all of these equations? 1.) The radius from the center of a nuclear to the different possible orbit of the electrons 2.) The velocity of a proto …

Hi all Ill start with saying I am very new to all this. I am a very geometric oriented person and I view things as images and not equations. So most times I can figure out and know …

How plank's constant and Avogadro number was determined?

Can somebody explain me the meaning of the words of Einstein Quantum mechanics is certainly imposing. But an inner voice tells me that it is not yet the real thing. The theory say …

Do you think the wavefunction is something which represents our knowledge of a system, or is it something physical? In the former case, could the same system be given a different w …

I have understood that an electron can be thought of both as a wave and as a particle. But I still don't understand why we can't give it a definite position...
