On the nonexistence of degenerate phase-shift multibreathers in a zigzag Klein-Gordon model
T. Penati, V. Koukouloyannis, M. Sansottera +2
In this work, we study the existence of low amplitude four-site phase-shift multibreathers for small values of the coupling in Klein-Gordon (KG) chains with interactions longer…

On the nonexistence of degenerate phase-shift discrete solitons in a dNLS nonlocal lattice
T. Penati, M. Sansottera, S. Paleari +2
We consider a one-dimensional discrete nonlinear Schr{ö}dinger (dNLS) model featuring interactions beyond nearest neighbors. We are interested in the existence (or nonexistence) of…

Tail resonances of FPU q-breathers and their impact on the pathway to equipartition
Tiziano Penati, Sergej Flach
Upon initial excitation of a few normal modes the energy distribution among all modes of a nonlinear atomic chain (the Fermi-Pasta-Ulam model) exhibits exponential localization on…
