Thermal boundary conditions in fractional superdiffusion of energy
Tomasz Komorowski, Stefano Olla
We study heat conduction in a one-dimensional {finite}, unpinned chain of atoms perturbed by stochastic momentum exchange and coupled to Langevin heat baths at {possibly} distinct…

Macroscopic diffusive fluctuations for generalized hard rods dynamics
Pablo A. Ferrari, Stefano Olla
We study the fluctuations in equilibrium for a dynamics of rods with random length. This includes the classical hard rod elastic collisions, when rod lengths are constant and equal…
