A thermal diode or rectifier is a system that transmits heat or energy in one direction better
than in the opposite direction. We investigate the influence of the distribution of energy …

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 …
