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

Multiple quantum NMR spin dynamics arising from a two-quantum/two-spin non-secular average dipolar Hamiltonian are solved exactly for an infinite one-dimensional (l-D) quantum spin 1/2 chain with nearest-neighbor dipole-dipole interactions and initially at thermal equilibrium in a Zeeman field.
