Resumen : | We discuss the non-Boltzmannian nature of quasi-stationary states in the Hamiltonian mean field (HMF) model, a paradigmatic model for long-range interacting classical many-body systems. We present a theorem excluding the Boltzmann–Gibbs exponential weight in Gibbs Γ-space of microscopic configurations, and comment a paper recently published by Baldovin and Orlandini [Phys. Rev. Lett. 96 (2006) 240602]. On the basis of the points here discussed, the ongoing debate on the possible application, within appropriate limits, of the generalized q-statistics to long-range Hamiltonian systems remains open. |
