# Totally asymmetric simple exclusion process on a tree lattice

#### Totally asymmetric simple exclusion process on a tree lattice

- Event time: 11:30am
- Event date: 19th September 2012
- Speaker: Dr Peter Mottishaw (School of Physics & Astronomy, University of Edinburgh)
- Location: Room 2511, James Clerk Maxwell Building (JCMB) James Clerk Maxwell Building Peter Guthrie Tait Road Edinburgh EH9 3FD GB

### Event details

The talk will begin by reviewing the one dimensional totally asymmetric simple exclusion process (TASEP) and its mean field theory. The model will then be generalised to a tree lattice with fixed branching number, b. Using general properties of the correlation functions for the TASEP on a network I will show that mean field theory becomes exact in the limit of large b for the tree network. Finally I will discuss the possible uses of this approach for improving the approximation for finite b beyond mean field theory.
