Chaos and Irreversibility

3:00 PM-5:00 PM
Room: Maybird

This minisymposium aims at augmenting the plenary talk by J. Robert Dorfman on the relation between transport properties of many-particle systems and their underlying chaotic dynamics. The speakers in this minisymposium will discuss the possibility of experimentally observing chaos in many article systems, and the modelling of thermodynamic transport properties by spatially extended chaotic maps of the plane. Special attention is devoted to entropy production fluctuations in nonequilibrium steady states, and to recent results of computer simulations of many-particle systems and turbulence.
