    "abstract": "We study the differences between the process of decoherence induced by\nchaotic and regular environments. For this we analyze a family of simple models\nwich contain both regular and chaotic environments. In all cases the system of\ninterest is a \"quantum walker\", i.e. a quantum particle that can move on a\nlattice with a finite number of sites. The walker interacts with an environment\nwich has a D dimensional Hilbert space. The results we obtain suggest that\nregular and chaotic environments are not distinguishable from each other in a\n(short) timescale t*, wich scales with the dimensionality of the environment as\nt*~log(D). Howeber, chaotic environments continue to be effective over\nexponentially longer timescales while regular environments tend to reach\nsaturation much sooner. We present both numerical and analytical results\nsupporting this conclusion. The family of chaotic evolutions we consider\nincludes the so-called quantum multi-baker-map as a particular case.",
