(a) What are the energy eigenvalues and eigenvectors during the interval 0 < t < T ? (b) What is the state of the system at time t = T ? (c) If the observable D = i | 1 aA 2 | + i | 2 aA 1 | were measured at time t = T , what are the possible results of the measurement? (d) What are the probabilities of obtaining each possible result? (e) For each possible result, give the state of the system after the measurement....
