# Overview of Renyi Entropy

#### Overview of Renyi Entropy

- Event time: 11:30am
- Event date: 15th March 2017
- Speaker: Mr Anthony Wood (School of Physics & Astronomy, University of Edinburgh)
- Location: Room 4325A, James Clerk Maxwell Building (JCMB) James Clerk Maxwell Building Peter Guthrie Tait Road Edinburgh EH9 3FD GB

### Event details

I will present an overview of Renyi entropy. This is a family of entropies that generalise the usual Shannon entropy, used as a tool to further detail probability distributions. I will show that this entropy satisfies the major “requirements” an entropy measure should have, and a neat physical interpretation for systems in thermal equilibrium.

I will then consider the Renyi entropy of a classical nonequilibrium system, in the Asymmetric Exclusion Process (ASEP). I will present results for the Renyi entropy that characterises behaviour across various phases, despite a nontrivial probability distribution.
