comment Study Quantum Physics
@Hal Swyers thank you for giving insight into importance of heat equation in understanding the Schrodinger equation. I wish I could get free e-copy of this book "who is fourier" else i will try buying it.

comment Derivation of Schrodinger equation for a system with position dependent effective mass
thank you for the answer but what i am asking is how to derive it within the regime of effective mass approximation and that too when the mass has a spatial profile... for example in the case of Al/GaAs high electron mobility transistor we have a position dependent mass.

comment Why is the valence band maximum at the gamma point in the bandstructure view of dispersion relation?
@genneth: I think the answer to the question lies in your hint that systems with inversion symmetry have band extrema at the gamma point. For example, graphene has no inversion symmetry. I will check it out and get back to you.

comment Why is the valence band maximum at the gamma point in the bandstructure view of dispersion relation?
@ron maimon I am asking about the structure of the top most filled band, the valence band. In cases like graphene occurrence of band maximum is not at the Gamma point.
