Energy thermalization pada model fermi-pasta-ulam-tsingou dengan pengaruh weak disorder

---

This final project discusses the effect of weak disorder on the thermalization process in the Fermi–Pasta–Ulam–Tsingou (FPUT) model, which is one of the classical systems in nonlinear dynamics based on Hamiltonian mechanics. In this study, two types of weak disorder are introduced, namely mass disorder and quadratic potential disorder. The research is conducted numerically through ti- me evolution simulations of the system with varying levels of disorder strength, specifically 0, 0.2, 0.4, and 0.8, up to a time of T = 105. The simulation results show that both types of disorder significantly accelerate the thermalization pro- cess, as the energy in the system becomes more evenly distributed among the normal modes. Moreover, it is observed that the greater the intensity of the disorder, the faster the system approaches a state near thermal equilibrium.
Keywords: FPUT, mass disorder, quadratic potential disorder, thermalization, weak disorder
