The hydrodynamic limit for the energy transport in a stochastically perturbed harmonic chain of oscillators

Tomasz Komorowski, Stefano Olla, Marielle Simon

We consider a pinned harmonic chain perturbed by random velocity flips, which conserve the total energy. Previous results have established the diffusive hydrodynamic limit for the…

Multitime fields and hard rod scaling limits

Pablo A. Ferrari, Stefano Olla

A Poisson line process is a random set of straight lines contained in the plane, as the image of the map , for each point of a Poisson…

Nonlinear fluctuations for a chain of weakly anharmonic oscillators with stochastic perturbation

Kohei Hayashi, Stefano Olla

We study the fluctuations of the phonon modes in a one-dimensional chain of anharmonic oscillators where the deterministic Hamiltonian dynamics is perturbed by random exchanges of…

Periodically forced pinned anharmonic atom chains

Shiva Darshan, Alessandra Iacobucci, Stefano Olla +1

Recent works proved a hydrodynamic limit for periodically forced atom chains with harmonic interaction and pinning, together with momentum flip. When energy is the only conserved q…

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…

Heat flow in a periodically forced, unpinned thermostatted chain

Tomasz Komorowski, Stefano Olla, Marielle Simon

We prove the hydrodynamic limit for a one-dimensional harmonic chain of interacting atoms with a random flip of the momentum sign. The system is open: at the left boundary it is at…
