Low-dimensional q-Tori in FPU Lattices: Dynamics and Localization Properties

Helen Christodoulidi, Christos Efthymiopoulos

This is a continuation of our study concerning q-tori, i.e. tori of low dimensionality in the phase space of nonlinear lattice models like the Fermi-Pasta-Ulam (FPU) model. In our…
