Time evolution of wave-packets in quasi-1D disordered media
A. Politi, S. Ruffo, L. Tessieri
We have investigated numerically the quantum evolution of a wave-packet in a quenched disordered medium described by a tight-binding Hamiltonian with long-range hopping (band rando…

Finite times to equipartition in the thermodynamic limit
J. De Luca, A. Lichtenberg, S. Ruffo
We study the time scale T to equipartition in a 1D lattice of N masses coupled by quartic nonlinear (hard) springs (the Fermi-Pasta-Ulam beta model). We take the initial energy to…
