    "abstract": "We analyze a microscopic decoherence model in which the total system is\ndescribed as a spin gas. A spin gas consists of N classically moving particles\nwith additional, interacting quantum degrees of freedom (e.g. spins). For\nvarious multipartite entangled probe states, we analyze the decoherence induced\nby interactions between the probe- and environmental spins in such spin gases.\nWe can treat mesoscopic environments (10^5 particles). We present results for a\nlattice gas, which could be realized by neutral atoms hopping in an optical\nlattice, and show the effects of non-Markovian and correlated noise, as well as\nfinite size effects.",
