#9:  Extra Credit*:  Using the time-dependent Schrodinger equation for an electron in a periodic potential and a uniform electric field, show that the wavefunction at time t is a linear combination of Bloch states, all of which have the wavevector k-eEt/h_bar.  *hint: assume the initial wavefunction to be a linear combination of Bloch states.
