First of all, Thanks a lot for your help!
I know understand the product of states. I also am familiar with the Dirac-notation.
I also know how to find the eigenvectors of a matrix (eigenvalues first, then solve for matrix - eigenvalue*I = 0 )
The only thing is that I don't know how to put...
Homework Statement
L.S.,
I'm breaking my head over this problem! To anyone who can help me out: thanks a lot!
Consider a two-point grid (point a en point b) and two electrons occupying those points, (they can both occupy one point at the same time), both wit spin-up or spin-down. Now, they...
Homework Statement
Hello,
I'm studying for my final exam on statistical physics, and I found an exercise of which I think it is really easy but I'm unsure of how to do it! So now I wonder if I actually don't understand what I'm doing at all!
The question is as follows:
Calculate for...
Thanks again!
Oke. Only positive integers are allowed for nx, ny, nz
Therefor, the surface of the paraboloid (right?) is four times 'too much'
so for a certain E, the amount of states (nx, ny, nz)
equals 1/4 \int\int sqrt (1+(4(a/b)^2)*r^2) r d \Theta dr
I put it in polar...
Thank you very much!
So then I put V(z,t) = is (1/2)kz^2,
Which gives me Ezn = (h/2pi)&sqrt(k/m)*(n + 0.5)?
And can I then transform that into (h^2)(k^2)*(n+0.5)/(2m)? <-- this is probably wrong?
Usually with just a particle in a LxLxL box I can 'count' the number of states with a...
When you consider a electron L×L×L box, I think I understand how to derive the DOS-spectrum.
Unfortunately, when a small change is made to the problem, I really don't understand what to do, so I probably don't understand the theory at all..
This is the question:
