A simple statistical explanation for the localization of energy in nonlinear lattices with two conserved quantities
arXiv:nlin/0312058 · doi:10.1103/PhysRevE.69.016618
Abstract
The localization of energy in the discrete nonlinear Schroedinger equation is explained with statistical methods. The partition function and the entropy of the system are computed for low-amplitude initial conditions. Detailed predictions for the long-time solution are derived.
