    Graduate Off-Diagonal Hamiltonian elements

    Thanks for the reply I think It's all slowly falling into place. I've not heard of the Rashba Hamiltonian but I'll try find it in a textbook somewhere. Thanks again for the help!

    Graduate Off-Diagonal Hamiltonian elements

    Actually I've just been thinking about it and I think it just has to do with interaction energies between states. Is this correct?

    Graduate Off-Diagonal Hamiltonian elements

    Hello, I just have a quick question about Quantum Mechanics. It's probably a bit basic but I'm trying to get my head around the off-diagonal Hamiltonian elements of a perturbation. We can assume the unperturbed Hamiltonian to be degenerate. If I have a Hamiltonian H=H_{0}+H' where the...

    Classical electrodynamics -Good conductor

    That makes sense but the question asks for a specific value of the frequency. Initially I thought I'd obtain an equation of the form \omega e^{-\omega} which has a definite maximum value.

    Classical electrodynamics -Good conductor

    Homework Statement The question given is an electromagnetic wave incident on a vacuum metal interface. The wave is incident normally. We're given that the metal is a good conductor i.e. \omega \tau <<1 where \tau is the collision time of the metal and omega is the angular frequency. The metal...
