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 Schrodinger equation is solved if these are the potentials and I'd like to have a better understanding of quantum...
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?
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...
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...
