Comment on “Resonance fluorescence near a photonic band edge: Dressed-state Monte Carlo wave-function approach”

Quang and John have, in a recent paper [Phys. Rev. A $56,$ 4273 (1997)], proposed a dressed-state Monte Carlo wave-function (MCWF) approach to a laser-driven two-level atom coupled to a structured radiation reservoir. In this Comment, we argue that this approach is at variance with the underlying physical idea of the MCWF technique, that it is at variance with basic formal requirements for the MCWF technique to apply, and that it produces spurious and unphysical quantitative results for wide ranges of parameters.
