In this paper it is shown that exact decoherence to minimal uncertaintyGaussian pointer states is generic for free quantum particles coupled to a heatbath. More specifically, the paper is concerned with damped free particleslinearly coupled under product initial conditions to a heat bath at arbitrarytemperature, with arbitrary coupling strength and spectral densities coveringthe Ohmic, subohmic, and supraohmic regime. Then it is true that there exists atime t_c such that for times t>t_c the state can always be exactly representedas a mixture (convex combination) of particular minimal uncertainty Gaussianstates, regardless of and independent from the initial state. This exact`localisation' is hence not a feature specific to high temperatures and weakdamping limit, but is rather a generic property of damped free particles.Comment: 4 pages, 1 figur
