defined psi_in #8

Open gvetaw opened 8 years ago

gvetaw commented 8 years ago

@andrewdurkiewicz @ion201 I defined the psi_in function to the file. According to the literature psi_in is a function that can be in the spin up or spin down basis so before the electron enters the magnetic field it has a superposition of the spin up spin down state.

here is the issue we have at the moment. We dont know how to normalize psi. Also, since the magnetic field portion has the potential, but that potential is zero everywhere else, that would mean that the wave is going through a barrier. Shouldn't there be reflection?

andrewdurkiewicz commented 8 years ago

Look at the wiki, I just posted our derivation (if we use momentum space)

gvetaw commented 8 years ago

The psi in stays normalized because it is just a psi at the being of the problem at t = 0. As for psi in the magnetic field I think we should also set t=0 until we see what the behavior of the ft is inside the field. Once we get a reasonable graph we can go back and worry about the time dependence and normalization.

well, maybe we should tackle this in 2d first. what psi are you using?

gvetaw commented 8 years ago

I did it first in 1d and I am now trying to define psi_m from 10.11

I was thinking we could just use matrix to define our phi? Assign I = x component and j to z . what do you think?
