DESCRIPTION:Quantum mechanical theories describing large N by N matrices o
 f oscillators can lead to an emergent space as N -> infinity. In the most 
 fully fledged version\, the emergent space is dynamical and gravitating. H
 owever\, there are also simpler\, lower dimensional versions of this pheno
 menon. One of the simplest occurs in the so-called quantum Hall matrix mod
 el\, in which a 2 dimensional space emerges and supports Chern-Simons dyna
 mics. I will describe how this solvable model leads to insights about the 
 emergence of space from matrices. In particular\, I will describe how the 
 emergent spatial locality is reflected in the entanglement structure of th
 e ground state of theory.
