Wigner-Eckart theorem. Note: there is no recording for PHYSICS739_AngularMomentum6. -
From DUNCAN O'DELL
Looked at general case of adding two angular momenta j1 and j2, and introduced the recursion method. -
From DUNCAN O'DELL
Started studying the addition of angular momentum using the lowering operator method. Introduced direct sums and direct products of Hilbert spaces for the coupled and… -

From DUNCAN O'DELL
Finished off this part of the course by looking at harmonic perturbations and also 2nd order time-dependent perturbation theory. Started some slides on ``What is a… -
From DUNCAN O'DELL
Generalized our treatment of first order transitions to include a slow switch on of the perturbation. -
From DUNCAN O'DELL
Showed how to find transition amplitudes from the Dyson series. Began analyzing 1st order perturbations constant in time except for being switched on at t=t0. -
