报告摘要:Over the past decade, significant efforts have been devoted to describing and classifying interacting gapped topological phases. However, investigations into interacting gapless topological phases remain very rare. In this talk, I will take a 1+1D exactly solvable model—the cluster Ising model—as an example, combined with my series of work in this newly emerging field, to explain the basic concepts and properties of gapless symmetry-protected topological phases.
