SOLVED: 5. (4 pts) Apply perturbation theory to the most general two-level system. The unperturbed Hamiltonian is H0 =and the perturbation isH1-x( V: V)with Va =V, Vaa and V real, so that H is hermitian. A is a constant that later will be set to 1(a) Find the exact energies for this two-level system. (b) Expand your result from (a) to second order in (and then set to 1). Verify that the series agree with the results from perturbation theory in Sections 6.1.2 and 6.1.3. Assume E > E(c) Setting
