Expectation values and energy.

There was a really interesting question, from a person in the back row on the right, on Tuesday

regarding the relationship between the energy, E1, which is both a parameter in the time-independent Schrodinger equation and the eigenvalue of the energy operator when applied to the ground state wave function. For the finite square well, and in most cases, ψ1 is an energy eigenstate, but not an eigenstate of kinetic energy. This video explores the relationship between the energy, E1 and the expectation values of the kinetic and potential energy.

Midterm 2 solutions

Here are solutions to midterm 2. I see that I did not write it in the solutions, but it is helpful for sp2 type integrals to recall that \(\...
