Unformatted text preview: eigenstate is  E 1 i = A (2  ± 1 i i  ± 2 i ) and it has an energy eigenvalue of Δ. The other eigenstate  E 2 i has an energy eigenvalue ofΔ. (1a) Find the normalization constant A, assuming it is real. (1b) Find  E 2 i in the { ± i i} basis. To remove arbitrariness in the overall phase, choose the coeﬃcient of  ± 1 i to be real. (1c) Suppose that at t = 0 the system is in the state  ± 2 i . What is the probability of being in this state for time t > 0?...
