Consider a two-level system which, in energy representation, is described by the Hamiltonian $H_0 = \begin{pmatrix} \epsilon_1 & 0\\ 0 & \epsilon_2 \end{pmatrix}$ mit $\epsilon_1 < \epsilon_2$. We are interested in the eigenenergies of the perturbed system $H = H_0 + V$ with $V = \lambda \begin{pmatrix} V_{11} & V_{12} \\ V_{21} & V_{22} \end{pmatrix}$, $V^\dagger = V$, $\lambda$ real. a) (7 pts) Calculate the eigenvalues up to second order in perturbation theory. b) (7 pts) Calculate the eigenvalues of $H$ exactly. In which limit does one obtain the perturbative result in a)?
