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. 

Linearity stabilizes discrete breathers

The study of the dynamics of 1D chains with both harmonic and nonlinear interactions, as in the Fermi–Pasta–Ulam (FPU) and related problems, has played a central role in efforts to identify the broad

Breathers and thermal relaxation as a temporal process: A possible way to detect breathers in experimental situations

Breather stability and longevity in thermally relaxing nonlinear arrays is investigated under the scrutiny of the analysis and tools employed for time series and state reconstruction of a dynamical

Discrete breathers and the anomalous decay of luminescence

Some years ago an anomaly was noted in the decay of luminescence in certain doped alkali halides. The anomaly was eventually explained using a factor 1 billion (109) slowdown in lattice relaxation, a

Early time evolution of a localized nonlinear excitation in the β-FPUT chain

We present the detailed dynamics of the particles in the β-Fermi–Pasta–Ulam–Tsingou (FPUT) chain after the initiation of a localized nonlinear excitation (LNE) by squeezing a central bond in the

Energy thresholds of discrete breathers in thermal equilibrium and relaxation processes.

TLDR
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

TLDR
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.

Asymptotic dynamics of breathers in Fermi-Pasta-Ulam chains.

TLDR
A numerical study of the asymptotic dynamics of breathers in finite Fermi-Pasta-Ulam chains at zero and nonzero temperatures finds that thermal fluctuations tend to lead to breather motion and more rapid decay.

Energy relaxation in nonlinear one-dimensional lattices.

TLDR
Energy relaxation in thermalized one-dimensional nonlinear arrays of the Fermi-Pasta-Ulam type is studied, finding that at long times relaxation is extremely slow due to the spontaneous appearance and persistence of energetic high-frequency stationary breathers.

TLDR
It is shown that raising the temperature can lead to enhanced signal propagation along the chain, resulting in thermal resonance effects akin to the resonance observed in arrays of bistable systems.

TLDR
It is shown that when the heat field strength is greater than a certain critical value, solitons can be generated in molecular dynamics simulations starting from random initial conditions and increases monotonically with the size of the system.
