Question:
a. Assuming that the Hamiltonian is invariant under time reversal, prove that the wave function for a spinless non-degenerate system at any given instant of time can always be chosen to be real.
b. The wave function for a plane-wave state at t = 0 is given by a complex function eip∙x/h. Why does this not violate time-reversal invariance?
