Evolution of the density matrix of large systems
The time dependent perturbation series for the density matrix is shown to be equivalent to an integral equation. This integral equation is given in the form of a series in the coupling parameter X, which is allways convergent when t→∞. The terms of this series can be represented by time retarded ope...

| Sumario: | The time dependent perturbation series for the density matrix is shown to be equivalent to an integral equation. This integral equation is given in the form of a series in the coupling parameter X, which is allways convergent when t→∞. The terms of this series can be represented by time retarded operators. |
