DESCRIPTION:The bulk-boundary correspondence is a key concept in understan
 ding quantum phases of matter. It relates topological features of the bulk
  of a quantum many-body system to exotic boundary phenomena. I will explor
 e some simple models of one-dimensional chains that exhibit this correspon
 dence\; examples of symmetry-protected topological phases of matter. I wil
 l explain how these ideas can persist even at phase transitions and in the
  presence of long-range (algebraically decaying) interactions.
