Prethermalization in a classical phonon field: Slow relaxation of the number of phonons
We investigate the emergence of an astonishingly long prethermal plateau in a classical phonon field, here, a harmonic chain with on-site pinning. Integrability is broken by a weak anharmonic on-site potential with strength λ. In the small λ limit, the approach to equilibrium of a translation invari...
