WebJun 12, 2024 · These are blocks of the perturbed Hamiltonian in the same matrix location as any blocks of the unperturbed Hamiltonian with a repeated eigenvalue. As we said earlier, the states in these block share any relevant symmetries. The perturbation can break one or more of these symmetries, resulting in energy corrections which lift the degeneracy.

WebChapter 5. Diagonalization 5.3. Minimal Polynomials Theorem 5.10. If A is a symmetric n nmatrix, then it has nreal eigenvalues (counted with multiplicity) i.e. the characteristic polynomial p( ) has nreal roots (counted with repeated roots). The collection of Theorems 5.7, 5.9, and 5.10 in this Section are known as the Spectral Theorem WebMay 30, 2024 · The equations in matrix form are d d t ( x 1 x 2) = ( 1 − 1 1 3) ( x 1 x 2) The ansatz x = v e λ t leads to the characteristic equation 0 = det ( A − λ I) = λ 2 − 4 λ + 4 = ( λ − 2) 2. Therefore, λ = 2 is a repeated eigenvalue. The associated eigenvector is found from − v 1 − v 2 = 0, or v 2 = − v 1; and normalizing with v 1 = 1, we have
