Intrinsically/Purely Gapless-SPT from Non-Invertible Duality Transformations
Linhao Li, Masaki Oshikawa, Yunqin Zheng
The Kennedy-Tasaki (KT) transformation was used to construct the gapped symmetry protected topological (SPT) phase from the symmetry breaking phase with open boundary condition, an…
When are Duality Defects Group-Theoretical?
Zhengdi Sun, Yunqin Zheng
A quantum field theory with a finite abelian symmetry may be equipped with a non-invertible duality defect associated with gauging . For certain , duality defects admit a…
Subsystem Non-Invertible Symmetry Operators and Defects
Weiguang Cao, Linhao Li, Masahito Yamazaki +1
We explore non-invertible symmetries in two-dimensional lattice models with subsystem symmetry. We introduce a subsystem -gauging procedure, called the s…
Classification of chiral fermionic CFTs of central charge
Philip Boyle Smith, Ying-Hsuan Lin, Yuji Tachikawa +1
We classify two-dimensional purely chiral conformal field theories which are defined on two-dimensional surfaces equipped with spin structure and have central charge less than or e…
Symmetry TFTs and Anomalies of Non-Invertible Symmetries
Justin Kaidi, Emily Nardoni, Gabi Zafrir +1
It is known that the 't Hooft anomalies of invertible global symmetries can be characterized by an invertible TQFT in one higher dimension. The analogous statement remains to be un…
Non-Invertible Duality Transformation Between SPT and SSB Phases
Linhao Li, Masaki Oshikawa, Yunqin Zheng
In 1992, Kennedy and Tasaki constructed a non-local unitary transformation that maps between a spontaneously symmetry breaking phase and the Halda…
