Topological versus Landau-like phase transitions
arXiv:1511.07460
Abstract
The study of continuous phase transitions triggered by spontaneous symmetry breaking has brought new concepts that revolutionized the way we understand many-body systems. Recently, through the discovery of symmetry protected topological phases, it is realized that quantum phase transition between states with the same symmetry but different topology can also occur continuously. Here we ask "what distinguishes these two types of phase transitions".
