Orienteering, daisies and spilt coffee: Simulations with non-Hamiltonian Dynamics
I will show a number of examples of systems which evolve via non-Hamiltonian algorithms. These are characterised by a lack of detailed balance (irreversible dynamics), a flow of ''stuff'' through the system and the attainment of a steady state. Examples include a model ecology ''daisyworld'', electrochemical deposition with and without levelling agents and the bunching phase transition of cyclists. I will discuss whether there exist fundamental laws relating to information flow which help to unite these various systems. Since I don't know the answer, this discussion may be limited, but there will be java movies.
This is a weekly series of informal talks given primarily by members of the soft condensed matter and statistical mechanics groups, but is also open to members of other groups and external visitors. The aim of the series is to promote discussion and learning of various topics at a level suitable to the broad background of the group. Everyone is welcome to attend..
