Thank you

I understand that the relationship between the phonon frequency and its wavenumber is the phonon dispersion. But is there a much more indepth definition of phonon dispersion and if i was asked to explain in a few lines (and in english not mathematical equations) what the phonon dispersion...

Sorry, this doesn't answer your question, but poses another. Could you please help me with the 2D proof? Maybe send it as an attached file to mosquisofly@gmail.com or post it here. Sorry once more and thank you.

@nasu, your link to Wikipedia was very helpful, and I'm very grateful. But i was hoping you could assist me again with another project. It is the derivation of the phonon dispersion relation using classical and quantum treatment in 1d, 2d and 3d. Please any help will be sincerely appreciated...

but can you help me out with an idea or something about the proof, because purchasing that book is kinda troublesome.

oops.. Sorry i didn't know.

okay, thanks.. but do you have a soft copy of the book or a link where i can get it from. pleeeeeeeeaaaaaaaaase.

I'm doing a literature review on dispersion relations, and I've been told that if i can derive the phonon dispersion relation, it would help my review. So i was wondering if anybody could help me with the derivation either through Quantum-mechanical approach or Semi-classical treatment of...
