Question:
Here is an application of the technique developed in Problem 7.34. Consider the Hamiltonian
(a) Find the projection operator PD (it’s a 3 x 3 matrix) that projects onto he subspace spanned by
Then construct the matrices H̅0 and H̅'.
(b) Solve for the eigenstates of H̅0 and verify…
i. That its spectrum is nondegenerate,
ii. That the nondegenerate eigenstate of H0
is also an eigenstate of H̅0 with the same eigenvalue.
(c) What are the “good” states, and what are their energies, to first order in the perturbation?
