How to fill out second order perturbation formory

How to fill out second order perturbation formory:

1. Start by gathering all the necessary information and equations related to the system under consideration. This includes the Hamiltonian of the unperturbed system, the perturbation term, and any additional information such as wavefunctions or energy levels.
2. Calculate the unperturbed eigenvalues and eigenstates of the system using the Hamiltonian of the unperturbed system. This step involves solving the Schrödinger equation for the unperturbed Hamiltonian.
3. Apply the perturbation term to the eigenvectors obtained in the previous step. This involves calculating the matrix elements of the perturbation operator between the unperturbed eigenvectors.
4. Use the second order perturbation theory formula to calculate the second order correction to the energies of the system. This formula involves summing over the perturbed states and constructing a series expansion.
5. Calculate the new eigenvalues by adding the second order correction term to the unperturbed energies obtained in step 2.
6. Determine the new wavefunctions and eigenstates of the perturbed system by applying the perturbation term to the original unperturbed eigenvectors and normalizing the resulting wavefunctions.
7. Verify your results by checking if the perturbed eigenstates are orthogonal and complete.
8. Make sure to properly format and present your results, including the final energies, corrected eigenstates, and any additional relevant information.
