Description
We solve a problem of quantum dynamics of two coupled Schroedinger equations. Utilizing a matrix transformation analogous to the Darboux method we find analytic solutions valid in special cases, 'quasiexact solutions'. The general conditions for matrix Darboux transformations are formulated. The method is applied to a special case of wave-packet dynamics
