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…

Effective diffusivities in periodic KPZ
Yu Gu, Tomasz Komorowski
For the KPZ equation on a torus with a spacetime white noise, it was shown in \cite{GK21,ADYGTK22} that the height function satisfies a central limit theorem, and the varianc…

Hydrodynamic limit for a chain with thermal and mechanical boundary forces
Tomasz Komorowski, Stefano Olla, Marielle Simon
We prove the hydrodynamic limit for a one dimensional harmonic chain with a random flip of the momentum sign. The system is open and subject to two thermostats at the boundaries an…
