The Fermi-Pasta-Ulam-Tsingou Recurrence Problem
Salvatore D. Pace, Kevin A. Reiss, David K. Campbell
We perform a thorough investigation of the first FPUT recurrence in the -FPUT chain for both positive and negative . We show numerically that the rescaled FPUT recurrence tim…

Behavior and Breakdown of Higher-Order Fermi-Pasta-Ulam-Tsingou Recurrences
Salvatore D. Pace, David K. Campbell
We investigate numerically the existence and stability of higher-order recurrences (HoRs), including super-recurrences, super-super-recurrences, etc., in the alpha and beta Fermi-P…
