Emergent Complexity in the Universe:  An Information-Entropic Approach

 

From atoms to stars, physically-bound systems result from the interplay between attractive and repulsive interactions. In this lecture, I will introduce a new measure of complexity called "Configurational Entropy". Inspired by Shannon's information entropy, I will show how the configurational entropy encodes information about the shape and the stability of various physical objects, and how it can be used as an efficient measure of emerging complexity for static and dynamic phenomena. Applications will include solitons, compact astrophysical objects, spontaneous symmetry breaking, and inflationary cosmology.
