Thanks for this answer!

I know what an eigenvalue equation is, but i don't know how to use this knowledge in this case. For the Hamilton Operator I think I have to use the Schrödinger equation H * phi(x) = E * phi(x) with H = -h^2/(2m) * nabla^2 But what is then the answer? Is it "E" is the Eigenvalue and...

Hi! i want to calculate the eigenvalues and the eigenstates of the momentum operator and the Hamilton operator of a free particle. How do i do this? Thanks for answers!

thanks for the answer :rolleyes:

Hi! If there are two operators A and B, which commute, what are the consequences of that to the measurement of the corresponding dynamic quantities?

Hi! I want to calculate the density of states in the 3D, free electron gas, but I don't know how to do this. Can somebody help me? Thanks!

Thanks very much! :smile:

Hello! Why is it the case, that the principle quantum number limits the values of the angular momentum quantum number like l <= n-1 How is it possible to derive this? Thank you for your answers.
