Question

a. Show that the solution of Schrodinger's equation for a conservative [10] quantum system is as: |?(t')? = U(t', t0)|?(t0)? and also show that U(t', t0) U†(t', t0) = 1. b. If ??A and ??B be two observables such that: [??A, ??B] = i ??C Where ??C is also an observable then Show that: ?A?B ? i|?C?| / 2. [10]

Show that the solution of Schrodinger's equation for a conservative quantum system is as: |̨(t')⌡ = U(t', t0)|̨(t0)⌡ and also show that U(t', t0) U†(t', t0) = 1. If A and B be two observables such that: [A, B] = i C Where C is also an observable then Show that: ΔAΔB ≥ i|〈C〈| / 2.
