** Problem 9.14 Develop time-dependent perturbation theory for a multilevel sys- tem, starting with the generalization of Equations 9.1 and 9.2: Hown = E.V. (11m) = Ohm [9.79] At time t = 0 we turn on a perturbation H'(t), so that the total Hamiltonian is H = H + H'(t). [9.80] (a) Generalize Equation 9.6 to read "(t) = { cm(t)\ne-it/ (9.81) and show that C. - [9.82] where = (m H'IV.). [9.83] (b) If the system starts out in the state n, show that (in first-order perturbation theory) en(1) 1 [9.84) * Çok_elEn-E.sk Á Hvx(") di h
