Unformatted text preview: E for which transmission is perfect. (ii) Although physically the energy is real and positive, it is often useful to view T ( E ) as a function of complex energy E . Show that T ( E ) has a pole in the complex E plane at the values of E which correspond to bound state energies of the square well. (iii) Repeat exercise (ii) for the single deltafunction potential using the results of the previous question. 6 . Suppose is a simultaneous eigenstate of two anticommuting Hermitian operators A and B . What can you say about the eigenvalues of A and B for the state ? Illustrate your point using the parity operator (chosen so that = 1 = ) and the momentum operator. 1...
