The equilibration of sinusoidally modulated distribution of the kinetic temperature is analyzed in the β-Fermi-Pasta-Ulam-Tsingou chain with different degrees of nonlinearity …
Low dimensional nonequilibrium steady-state (NESS) systems are essential in understanding the microscopic origins of macroscopic laws. A one-dimensional chain …
We show numerically that including soft-sphere type collisions in the celebrated Fermi-Pasta- Ulam ($ FPU $) chain completely alters the thermal transport characteristics. The resulting …

We investigate bifurcation and chaos in one dimensional chains of small particles, exploring two new models, one having sixth-order potential, and the other, the deformed model with …
