Exponentially long times to equipartition in the thermodynamic limit
by Luisa Berchialla, Antonio Giorgilli and Simone Paleari

Abstract: We investigate with numerical methods the scaling of the relaxation time to equipartion in the celebrated Fermi--Pasta--Ulam model. Our numerical results strongly suggest that the time increases exponentially with an inverse power of the specific energy. Such a scaling remains valid in the thermodynamic limit.
