Discrete breathers on symmetry-determined invariant manifolds for scalar models on the plane square lattice
Discrete breathers symmetry-determined invariant manifolds scalar models plane square lattice

A group-theoretical approach for studying localized periodic and quasiperiodic vibrations in 2D
and 3D lattice dynamical models is developed. This approach is demonstrated for the scalar mod-

Feigenbaum Cascade of Discrete Breathers in a Model of DNA
Feigenbaum Cascade of Discrete Breathers Model of DNA

We demonstrate that period-doubled discrete breathers appear from the anti-continuum limit of
the driven Peyrard-Bishop-Dauxois model of DNA. These novel breathers result from a stability
overlap be...
Discrete breathers at the interface between a diatomic and monoatomic granular chain
Discrete breathers at the interface diatomic monoatomic granular chain

In the present work, we develop a systematic examination of the existence, stability and dynamical properties of a discrete breather at the interface between a diatomic and a monoatomic granular chain...
