Summary: ``We use the microscopic derivation of the Jaynes-Cummingsmodel master equation under field losses to study the dynamics ofinitial field-qubit states in the single-excitation manifold andbeyond. We show that field-qubit detuning, as well as finitetemperature, modify the effective decay rate of the system usingmeasures like field-qubit purity and concurrence for the case ofone-excitation, and for initial Fock states for more excitations. Forinitial semi-classical states of the field, we show that themicroscopic approach, in phase space, provides an evolution to thermalequilibrium that is smoother than the one provided by the standardphenomenological approach.''
