    "abstract": "We construct generally applicable small-loss rate expansions for the density\noperator of an open system. Successive terms of those expansions yield\ncharacteristic loss rates for dissipation processes. Three applications are\npresented in order to give further insight into the context of those\nexpansions. The first application, of a two-level atom coupling to a bosonic\nenvironment, shows the procedure and the advantage of the expansion, whereas\nthe second application that consists of a single mode field in a cavity with\nlinewidth $\\kappa$ due to partial transmission through one mirror illustrates a\npractical use of those expansions in quantum measurements, and the third one,\nfor an atom coupled to modes of a lossy cavity shows the another use of the\nperturbative expansion.",
