Im trying to learn transport processes and the Boltzmann transport equation. What books do you guys recommend for beginners? Thanks!

Hi. I'm wondering how different potentials, such as the Dirac-Delta potential, linear potential, quandratic potenial, etc., are implemented experimentally. I only understand how the Schrödinger equation is solved if these are the potentials and I'd like to have a better understanding of quantum...

thank you very much by the way

oh ok i get it now. ill rework my whole solution

yes thank you i reworked that part of the solution divergene of E = (1/epsilon) divergence of (D - P) = (1/epsilon) {divergence of D - divergence of P} = 1/epsilon (p_free - (-p_bound)) since p_free + p_bound = p , and it is given that p = 0 thus divergence of E = 0 is that the only correction?

hm.. i might have written the wrong thing in my post but here is my handwritten solution

Homework Statement given a medium in which p=0, j=0 but where the polarization vector P=P(r,t). Derive the wave equation satisfied by E and B.Homework Equations i started with the 4 basic Maxwells equations ∇ · D = ρ (1) ∇ · B = 0 (2) ∇ × E = −∂B/∂t (3) ∇ × H = J + ∂D/∂t (4) and with the...

thank you

hello, i am trying to learn the derivation of the momentum operator and i found 2 ways of deriving it. one is using Fourier transform and the other is taking the time derivative of the expectation value of x. i just want to know what is the physical interpretation of the time rate of change...
