摘要:
Topological order is a new type of quantum state beyond Laudau paradigm. Recently, many different systems with topologically ordered ground states on spin model (we call them symmetry protected topological orders) were found. How to classify symmetry protected topological orders and how to describe the quantum phase transitions between them (topological quantum phase transitions)? What's topological field theory of them? We try to answer these questions.
