Exponential localization of odd, even, and multi-pulse discrete breathers in Fermi–Pasta–Ulam–Tsingou lattices
Discrete breathers are spatially localized periodic solutions in nonlinear lattices. The existence of odd and even symmetric single-pulse and multi-pulse discrete breathers has been proved in the one-dimensional Fermi–Pasta–Ulam–Tsingou lattices with even interaction potentials [Yoshimura and Doi, J...
