Stages of dynamics in the Fermi-Pasta-Ulam system as probed by the first Toda integral
H. Christodoulidi, C. Efthymiopoulos
We investigate the long term evolution of trajectories in the Fermi-Pasta-Ulam (FPU) system, using as a probe the first non--trivial integral in the hierarchy of integrals of t…

Extensive packet excitations in FPU and Toda lattices
H. Christodoulidi
At low energies, the excitation of low frequency packets of normal modes in the Fermi-Pasta-Ulam (FPU) and in the Toda model leads to exponentially localized energy profiles which…

The effect of long-range interactions on the dynamics and statistics of 1D Hamiltonian lattices with on-site potential
H. Christodoulidi, T. Bountis, L. Drossos
We examine the role of long--range interactions on the dynamical and statistical properties of two 1D lattices with on--site potentials that are known to support discrete breathers…
