Diffusion of heat, energy, momentum, and mass in one-dimensional systems
Diffusion of heat, energy, momentum, and mass in one-dimensional systems
We study diffusion processes of local fluctuations of heat, energy, momentum, and mass in three paradigmatic one-dimensional systems. For each system, diffusion processes of four physical quantities are simulated and the cross correlations between them are investigated. We find that, in all three systems, diffusion processes of energy and mass …
