    "abstract": "We present phase-space techniques for the modelling of spontaneous emission\nin two-level bosonic atoms. The positive-P representation is shown to give a\nfull and complete description and can be further developed to give exact\ntreatments of the interaction of degenerate bosons with the electromagnetic\nfield in a given experimental situation. The Wigner representation, even when\ntruncated at second order, is shown to need a doubling of the phase-space to\nallow for a positive-definite diffusion matrix in the appropriate Fokker-Planck\nequation and still fails to agree with the full quantum results of the\npositive-P representation. We show that quantum statistics and correlations\nbetween the ground and excited states affect the dynamics of the emission\nprocess, so that it is in general non-exponential.",
