Bulk-boundary correspondence in Projected Entangled Pair States
Projected Entangled Pair States form a framework for the description of quantum many-body systems which provides a natural duality between bulk and boundary properties. In this talk, I will explain this duality and show how it can be used to characterize entanglement properties and low-energy behavior of quantum many-body systems, and to understand the way in which topological order is related to properties at the boundary.
