I understand a and b but am stuck on c and d. Need outline of solution
Attractive delta function potential with step function
Similar problem might show up on my test tomorrow so I need to know how to do this one properly.
Finite Square Well Within An Infinite Square Well
For some reason I cannot end up with the expression in part A. If someone could go through this problem I would appreciate it. PS. The professor did not respond to my question whether there was a typo in the equation in part A. Since I cannot end up with the equation in part A and since it was suggested that the equation is ...continues
Prove that d(ax) = d(x)/|a| where d(x) is the Direc delta function and d stands for the Greek letter delta.
Often the relative probability of finding an atom in its excited state at time t is given by |psi(t)|^2 ~ e^(-2t/T), where T is the lifetime of the excited state. Normalize this probability distribution, and when does the probability drop to half the maximum value?
Energy eigen states and wave functions of an infinite square well
Show a detailed derivation for the time independent Schroedinger Equation for an 1-d square well , symmetric about the origin, with a dimension of L (-L/2 to 0 to +L/2).
A one-dimensional quantum well of width 19 nm is created, and measurements show that the energy difference between the ground state and the first excited state is 0.19 eV. What is the effective mass of the electron in the well? Answer in units of kg.
(A)A particle with spin 1 has orbital angular momentum L_lowercase=0. What are the possible values for the total angular momentum Quantum number j? (B)The same particle has L_lowercase=3. What are the possible values for j? I need to know how to do a problem like this, detailed solution please.
A particle has spin 1, so that m_s=-1,0 or 1. Derive the matrices which correspond to S_x, S_y and S_z.
