A Liouville-space method for the decoupling of the polarization propagator equation of motion

Statistical ensemble averages based on Liouville space matrix elements are used to introduce an alternative approach to the decoupling of the polarization propagator equation of motion. To this end, an appropriate ansatz for the (energy) propagator is introduced in the scenario of the superoperator...
