Graduate Good guide for fractional quantum hall
Hi everyone, does anybody now some good pedagogical materials to learn fractional quantum hall effect? I have a book of J.K.Jain, but it seems to me not a good one. Thanks- knightq

How to read review book or paper
Thanks ZapperZ, I think maybe i don't expose my problem clearly.Actually I don't know to what degree i should stop when i read the book of Tinkham or De gennes.Do I just need to know the main idea and features or I must understant superconductor deeply?Take the BSC theory Superconductor as...- knightq

How to read review book or paper
Hi everyone, I have a very general question about how to read a review book or paper? My tutor want to me read the book of deGennes and Tinkhan to start learning superconductor. Although I can unserstand the main features and even calculation,but i still can't "understand" BCS theory, I don't...- knightq

Graduate Problem about scattering amptitude
Take the scattering of photon and electron as example, we first figure out the amptitude for transition definte polarization, say f(ϵα(k),ϵα′(k′)) If the initial photon is unpolarized and the final polarization is not observed, we need to average the initial polarization and sum over the...- knightq

Graduate Why do we only average and sum over two independent polarizations in scattering?
Take the scattering of photon and electron as example, we first figure out the amptitude for transition definte polarization, say f(\epsilon_{\alpha}(\textbf{k}),\epsilon_{\alpha'} (\textbf{k}')) If the initial photon is unpolarized and the final polarization is not observed, we need to...- knightq

Graduate Question about equivalence principle
then what the gravity in case A is? if I am a man in the rocket, i want to a explanation of the gravity or the fact every thing around in rocket is falling, how could I explain? For this statement "In a reference frame that is in free fall, the laws of physics are the same as if there were no...- knightq

Graduate Question about equivalence principle
acceleration do not generate curvature, it can be treat just in special relativity.And do you answer my question?- knightq

Graduate Question about equivalence principle
Let me restate my problem in a more clear way i think. Situation A: a accelerated rocket in flat spacetime. the observer in the rocket could think he is in a gravitation field equivalently.All experiments he do are like in a gravitation field downward. SituationB: a apple falls down under...- knightq

Graduate How is gravity described mathematically in general relativity?
I mean the "false" force opposite to the direction of acceleration, such like the centrifugal force, which you must considerate in the stationary frame.- knightq

Graduate How is gravity described mathematically in general relativity?
I mean what is the origin of the inertia force. I know " the fact that your worldline is not a geodesic" Is it real gravity force? Obviously there is no source to produce this force. And according to what I learn ,the curvature=gravity.- knightq

Graduate How is gravity described mathematically in general relativity?
If I move with constant acceleration, say accelerate my car, in mincowski spacetime (flat), will I feel a inertia force? If so, where it come from? If it comes from gravity, does this conflict with the previous presumption(flat spacetime)?- knightq
