(a) Show that Ψ( x,t ) = ± mω π ¯ h ¶ 1 / 4 exp (mω 2¯ h " x 2 + a 2 2 ‡ 1 + ei 2 ωt · + i ¯ ht m2 axeiωt #) satisﬁes the timedependent Schr¨odinger equation for the harmonic oscillator potential. Here a is any real constant with the dimensions of length. (b) Find  Ψ ( x,t )  2 , and describe the motion of the wave packet. (c) Compute h x i and h p i , and check that Ehrenfest’s theorem is satisﬁed: m d dt h x i = h p i and d dt h p i =h dV dx i . —— End ——...
