# Breathers and thermal relaxation in Fermi-Pasta-Ulam arrays.

@article{Reigada2003BreathersAT, title={Breathers and thermal relaxation in Fermi-Pasta-Ulam arrays.}, author={Ramon Reigada and Antonio Sarmiento and Katja Lindenberg}, journal={Chaos}, year={2003}, volume={13 2}, pages={ 646-56 } }

Breather stability and longevity in thermally relaxing nonlinear arrays depend sensitively on their interactions with other excitations. We review numerical results for the relaxation of breathers in Fermi-Pasta-Ulam arrays, with a specific focus on the different relaxation channels and their dependence on the interparticle interactions, dimensionality, initial condition, and system parameters.

The energy thresholds of discrete breathers in thermal equilibrium and the energy threshold of long-lived discrete Breathers which can remain after a long time relaxation are analytically estimated for nonlinear chains.

### Effect of Discrete Breathers on the Specific Heat of a Nonlinear Chain

It is concluded that DBs affect specific heat of the nonlinear chain, and for the case of hard-type (soft-type) anharmonicity, they reduce (increase) the specific heat.
