报告摘要:Over the past decade, significant efforts have been devoted to describing and classifying gapped strongly correlated topological phases. However, investigations into gapless strongly correlated topological states remain very rare. In this talk , we will discuss the possible topological properties and classifications of the simplest class of gapless quantum phase of matter - quantum critical points (states), and try to establish novel bulk-edge correspondences within gapless phase of matter.
