Periodic Orbits in Fermi-Pasta-Ulam-Tsingou Systems
Periodic Orbits in Fermi-Pasta-Ulam-Tsingou Systems
The FPUT paradox is the phenomenon whereby a one-dimensional chain of oscillators with nonlinear couplings shows non-ergodic behavior. The trajectory of the system in phase space, with a long wavelength initial condition, closely follows that of the Toda model over short times, as both systems seem to relax quickly to …
