Nonlinearity and constrained quantum motion

The dynamical equation satisfied by the density matrix, when a quantum system is subjected to one or more constraints arising from conserved quantities, is derived. The resulting nonlinear motion of the density matrix has the property that the evolution is independent of the specific composition of...
