The quantum dynamics of a semi-infinite homogeneous harmonic chain is studied. Assuming the system to be in its ground state, a harmonic motion, A sin(or), is imposed on the mass at the beginning of the chain. The quantum state of the system for t > 0 is calculated by means of the evolution operator
