Strange correlator and string order parameter for non-invertible symmetry protected topological phases in 1+1d
Da-Chuan Lu, Fu Xu, Yi-Zhuang You
In this paper, we construct strange correlators and string order parameters for non-invertible symmetry protected topological phases (NISPTs) in 1+1d quantum lattice spin models. T…

Deconfined criticality as intrinsically gapless topological state in one dimension
Sheng Yang, Fu Xu, Da-Chuan Lu +3
Deconfined criticality and gapless topological states have recently attracted growing attention, as both phenomena go beyond the traditional Landau paradigm. However, the deep conn…
