Kinetic limit for a chain of harmonic oscillators with a point Langevin thermostat
Tomasz Komorowski, Stefano Olla
We consider an infinite chain of coupled harmonic oscillators with a Langevin thermostat attached at the origin and energy, momentum and volume conserving noise that models the col…
Effective mass of the polaron -- revisited
Wojciech Dybalski, Herbert Spohn
Properties of the energy-momentum relation for the Fröhlich polaron are of continuing interest, especially for large values of the coupling constant. By combining spectral theory w…
High frequency limit for a chain of harmonic oscillators with a point Langevin thermostat
Tomasz Komorowski, Stefano Olla, Lenya Ryzhik +1
We consider an infinite chain of coupled harmonic oscillators with a Langevin thermostat at the origin. In the high frequency limit, we establish the reflection-transmission coeffi…
Reflected Brownian motions in the KPZ universality class
Thomas Weiss, Patrik Ferrari, Herbert Spohn
This book presents a detailed study of a system of interacting Brownian motions in one dimension. The interaction is point-like such that the -th Brownian motion is reflected fr…
On invariants for the Poincare equations and applications
Valeriy Imaykin, Alexander Komech, Herbert Spohn
We extend the Noether theory of invariants to the Poincare equations. We apply this extension to the Maxwell-Lorentz equations coupled to the Abraham rotating extended electron wit…
On Time Correlations for KPZ Growth in One Dimension
Patrik L. Ferrari, Herbert Spohn
Time correlations for KPZ growth in 1+1 dimensions are reconsidered. We discuss flat, curved, and stationary initial conditions and are interested in the covariance of the height a…
