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…
Boundary Thermalization in Superdiffusive Energy Transport
Tomasz Komorowski, Stefano Olla
We study energy transport in a finite one-dimensional unpinned harmonic chain with stochastic nearest-neighbor momentum exchanges and Langevin heat baths at its endpoints. Such sys…
The Gaussian structure of a perturbed KPZ
Yu Gu, Tomasz Komorowski
We study the KPZ equation on a circle with an additive spatial perturbation , where is a spacetime white noise and is a s…
Periodically Driven anharmonic chain: Convergent Power Series and Numerics
Pedro L. Garrido, Tomasz Komorowski, Joel L. Lebowitz +1
We investigate the long time behavior of a pinned chain of oscillators, indexed by . The system is subjected to an external driving force on the parti…
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…
Convergent Power Series for Anharmonic Chain with Periodic Forcing
Pedro L. Garrido, Tomasz Komorowski, Joel L. Lebowitz +1
We study the propagation of energy in one-dimensional anharmonic chains subject to a periodic, localized forcing. For the purely harmonic case, forcing frequencies outside the line…
Homogenization of stable-like operators with random, ergodic coefficients
Tomasz Klimsiak, Tomasz Komorowski, Lorenzo Marino
We show homogenization for a family of -valued stable-like processes , , whose (random) Fourier symbols equal $q_ε(x,ξ;θ)=\frac{1}{ε^…
