"Irreversibility and dissipation in multiple-scale systems"


Abstract

Systems with disparate timescales are ubiquitous in physics and biology. 
Efficient modeling dictates to restrict the description to the slower 
processes and not to fully resolve the faster ones. I will discuss this 
general issue in stochastic systems with multiple timescales. In 
particular, I will address the behavior of thermodynamics upon changing 
the level of resolution. I will show how for non-equilibrium systems, 
under quite general conditions, properties of the fast dynamics still 
affect thermodynamics on the slower scales therefore compromising a 
description of the full system in terms of slow variables only.
Finally, I will give two relevant examples concerning Brownian motion 
and a simple biochemical network.
