AB Using the Hubbard representation for SU(2), we write the time-evolution operator of atwo-level system in the disentangled form. This allows us to map the corresponding dynamical lawinto a set of nonlinear coupled equations. In order to find exact solutions, we use an inverse approachand find families of time-dependent Hamiltonians whose off-diagonal elements are connected withthe Ermakov equation. A physical model with the so-obtained Hamiltonians is discussed in thecontext of the nuclear magnetic resonance phenomenon.
