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.
