Abstract. A class of bound-state problems which represent the coupling of a two-level atom with a two-dimensional supersymmetric system involving two shape-invariant potentials was introduced in a previous paper. We study in this second paper the quantum dynamics and the entanglement for two models with different coupling Hamiltonians.
