A three-state system has a complete orthonormal set of states |1), |2), [3). With respect to this basis the operators ÊĤl and B have matrices (1 0 ÊU = hw 0 -1 0 0 -1 Êß = b0 0 1 0 10 where w and b are real constants. (a) Are Ĥ and B Hermitian? |(b) Write down the eigenvalues of ÎĤ and find the eigenvalues of B. Solve for the eigenvectors of both Ĥ and B. Explain why neither matrix uniquely specifies its eigenvectors. (c) Show that Ĥ and B commute. Give a basis of eigenvectors common to Ĥ and B.
