In a recent paper, Phys. Rev. Lett. 105 260601 (2010) [arXiv:1008.1421],Andrade et al., argued that classical particles confined in a parabolic trap atT=0 distribute themselves in accordance with the Tsallis statistics. To provetheir point the authors performed molecular dynamics simulations. Here we showthat the model of Andrade et al. can be solved exactly. The distribution ofparticles at T=0 has nothing to do with the Tsallis entropy and is determinedsimply by the force balance.
