On modulational instability and energy localization in anharmonic lattices at finite energy density
Yuriy A. Kosevich, Stefano Lepri
The localization of vibrational energy, induced by the modulational instability of the Brillouin-zone-boundary mode in a chain of classical anharmonic oscillators with finite initi…

The Gallavotti-Cohen Fluctuation Theorem for a non-chaotic model
S. Lepri, L. Rondoni, G. Benettin
We test the applicability of the Gallavotti-Cohen fluctuation formula on a nonequilibrium version of the periodic Ehrenfest wind-tree model. This is a one-particle system whose dyn…
