1. ### Relativity General Relativity by Robert M. Wald

Robert M. Wald (general relativity) prerequirments I wish to read ch 1 to ch 6 from the book "General Relativity" by Robert M. Wald in full mathematical generality. [I do not have any considerable background in differential geometry. I'm a physics graduate student with some background in...
2. ### Ising model

Choose a + site. Join it to each neighbor by a line. we need to draw gamma lines. Now do this for all + sites. So total lines = gamma*N(+). In this process i) between any (+,+) pair there will be two lines (one when we draw line from 1st + to 2nd +, other when we draw line from 2nd + to 1st +)...
3. ### Bra-kets and operator formalism in QM - Expectation values of momentum

My solutions are here, have a look..
4. ### Basic Energy Problem (Concept)

If a particle moves on a frictionless rigid surface, due to the fact that this surface constrains the motion of the particle, we have an additional force acting (locally) perpendicularly to the surface.
5. ### Negative work and energy

Have a look..
6. ### Kinetic Energy of many-particle systems

Have a look..
7. ### Graduate Classical Mechanics Problem Book

My graduate course (2 sem) follows Goldstein (All chapters :surprised). Can anyone suggest me a book with solved problems on such advanced topics?

9. ### Reference books on Elementary particles,Statistical mechanics

I need some reference books on the following.... My 3rd year 2nd sem Undergraduate physics syllabus has a part like this- (I have 2 sem q.m., 1 sem special relativity as background.) The nuclear two-body problem and simple theory of the deuteron. Elementary particles: Baryons...
10. ### Can we apply superposition principle for states in Fock space?

Thanks Neumaier...:smile:
11. ### Density matrix off-diagonal elements

For a system with time Independent hamiltonian , in the basis of energy eigen kets, every off diagonal element between two kets corresponding to two distinct energy eigen values will oscillate with Bohr Frequency.
12. ### Reference for Axiomatic Quantum Statistical Mechanics

I have gone through two volumes of Cohen (Quantum Mechanics). Now I need a book on Quantum Statistical Mechanics. The book should use axiomatic formulation using density matrix. Please give me a suggestion. ( I'm also introduced with 2nd quantization slightly) Thanks for any help in advance.

16. ### Electronics books

J. David Irwin, R. Mark Nelms- Basic Engineering Circuit Analysis- (Wiley) is my choice. Go here to get pdf version - http://gen.lib.rus.ec/ Search and download. ***In the mirrors list click on "free-books.us.to" #It has many coloured pages so the size is a bit large (160 MB).
