Existence and exponential localization of multi-pulse discrete breathers in the FPUT lattice
Kazuyuki Yoshimura (Tottori Univ.) CAS2024-42 NLP2024-72
Abstract (in Japanese) (See Japanese page) 
(in English) Discrete breathers (DBs) are spatially localized periodic solutions in nonlinear lattices. We have proved the existence of multi-pulse DBs in one-dimensional infinite Fermi-Pasta-Ulam-Tsingou (FPUT) lattices with even interaction potentials. Exponential localization of those DBs also has been proved. The multi-pulse DB consists of an arbitrary number of the odd-like and/or even-like primary DBs located separately on the lattice. The odd and even symmetric single-pulse DBs are included as particular cases.
