    "abstract": "We develop a method to determine spatial configurations to realize\ndecoherence-free subspaces for spatially extended multi-particle systems. We\nhave assumed normal reservoir behavior including translational invariance of\nthe reservoir and preparation in stationary states or mixture thereof and weak\nMarkovian system-reservoir coupling that requires energy transfer. One\nimportant outcome of our method is a proof that there does not exist a\nmulti-particle decoherence-free subspace in such systems except in the limit\nthat the spatial extent of the system becomes infinitesimal.",
