Symmetry TFTs for Non-Invertible Defects
Justin Kaidi, Kantaro Ohmori, Yunqin Zheng
Given any symmetry acting on a -dimensional quantum field theory, there is an associated -dimensional topological field theory known as the Symmetry TFT (SymTFT). The Sym…
Boson-fermion duality with subsystem symmetry
Weiguang Cao, Masahito Yamazaki, Yunqin Zheng
We explore an exact duality in d between the fermionization of a bosonic theory with a subsystem symmetry and a fermionic theory with a subsyst…
Non-Invertible Symmetries of SYM and Twisted Compactification
Justin Kaidi, Gabi Zafrir, Yunqin Zheng
Non-invertible symmetries have recently been understood to provide interesting contraints on RG flows of QFTs. In this work, we show how non-invertible symmetries can also be used…
Decorated Defect Construction of Gapless-SPT States
Linhao Li, Masaki Oshikawa, Yunqin Zheng
Symmetry protected topological (SPT) phases are one of the simplest, yet nontrivial, gapped systems that go beyond the Landau paradigm. In this work, we study an extension of the n…
