This second part deals with applications of a general method to describe thequantum time evolution determined by a Schroedinger equation withtime-dependent Hamiltonian. A new aspect of our approach is that we find allsolutions starting from one special solution. The two main applications arereviewed, namely the Bloch equations and the harmonic oscillator withtime-dependent frequency. Even in these well-known examples some new resultsare obtained.

On the von Neumann equation with time-dependent Hamiltonian. Part II: Applications
