A certain 3-level system can have three values of energy associated with 3 stationary states: Energy state 0 1> 2> 2w 13> (a) An operator is written in the following form: Q = a 1 >< 1 + b(|2>< 3|+|3><2) with 0<<b. What will be the outcome if we measure the operator Q (b) If at time t = 0, the operator Q was measured, and the largest eigenvalue was obtained, write the wavefunction at any later time t. (c) If Ĥ was measured at any later time t, what might we get and with what probability. 5. Consider a three-level system where the Hamiltonian and observable A are given by the matrix A-P A = hw 010 101 0 10 100 0 10 0 0 1 (a) What are the possible values obtained in a measurement of A (b) Does a state exist in which both the results of a measurement of energy E and observable A can be predicted with certainty? Why or why not? (c) Two measurements of A are carried out, separated in time by t. If the result of the first measurement is its largest possible value, determine the expectation value < (t) A)) > for the second measurement. 6. Consider a two level system, where the matrix representation of the position operator and its eigenvectors are given by: Activate Windows Go to Sellings to activate Windows.
