q-Breathers in the diatomic β-Fermi–Pasta–Ulam–Tsingou chains
q -Breathers (QBs) represent a quintessential phenomenon of energy localization, manifesting as stable periodic orbits exponentially localized in normal mode space. Their existence can hinder the thermalization process in nonlinear lattices. In this work, we employ the Newton’s method to identify QB...
