REDUCED CONTROL DYNAMICS FOR COMPLEX QUANTUM-SYSTEMS

A reduced dimensional control dynamics formulation is presented for an arbitrary number of degrees of freedom. The traditional control feedb ack partial differential equation now becomes a small set of ordinary differential equations amenable to efficient numerical solution. This approach is capable of. finding optimal solutions with only a few feed back iterations, thereby dramatically reducing the effort to obtain co ntrol designs. As an example, the reduced formalism is applied to sele ctive dissociation of a triatomic molecule.
