Question
For a certain system, the operator corresponding to the quantity Aˆ does not commute with the Hamiltonian and also
has eigenvalues a1, a2 and eigenfunctions
respectively, where | u1⟩ and | u2⟩ are eigenfunctions of the Hamiltonian with eigenvalues E1 and E2.
a) If at time t = 0 the system is in the state | φ1⟩, show that the expected value of Aˆ at time t is
