Effective Hamiltonian for traveling discrete breathers in the FPU chain
Michael Kastner, Jacques-Alexandre Sepulchre
For the Fermi-Pasta-Ulam chain, an effective Hamiltonian is constructed, describing the motion of approximate, weakly localized discrete breathers traveling along the chain. The ve…

Energy thresholds for discrete breathers
Michael Kastner
Discrete breathers are time-periodic, spatially localized solutions of the equations of motion for a system of classical degrees of freedom interacting on a lattice. An important i…

Breathers in a model of a polymer with secondary structure
Michael Kastner, Tomas J. Lazaro
A simple model of a polymer is considered: a chain of (different) point masses, connected by harmonic springs, embedded in two dimensional space. In order to determine conditions f…
