Exact density matrix elements for a driven dissipative system described by a quadratic Hamiltonian

Abstract For a prototype quadratic Hamiltonian describing a driven, dissipative system, exact matrix elements of the reduced density matrix are obtained from a generating function in terms of the normal characteristic functions. The approach is based on the Heisenberg equations of motion and operato...
