Instability dynamics of nonlinear normal modes in the Fermi–Pasta–Ulam–Tsingou chains
Nonlinear normal modes are periodic orbits that survive in nonlinear chains, whose instability plays a crucial role in the dynamics of many-body Hamiltonian systems toward thermalization. Here we focus on how the stability of nonlinear modes depends on the perturbation strength and the system size t...
