    "abstract": "Classical properties of an open quantum system emerge through its interaction\nwith other degrees of freedom (decoherence). We treat the case where this\ninteraction produces a Markovian master equation for the system. We derive the\ncorresponding distinguished local basis (pointer basis) by three methods. The\nfirst demands that the pointer states mimic as close as possible the local\nnon-unitary evolution. The second demands that the local entropy production be\nminimal. The third imposes robustness on the inherent quantum and emerging\nclassical uncertainties. All three methods lead to localized Gaussian pointer\nstates, their formation and diffusion being governed by well-defined quantum\nLangevin equations.",
