Holographic Topological Insulator
  This research highlight (originally published at http://www.ntu.edu.sg/ias/newsletters/Documents/APPN/APPNv5n2May2016-lowres.pdf) introduces recent developments in Topological Insulators and Holography, and provides an overview of how one can construct a holographic bulk topological insulator from a boundary Chern insulator with small gap.
