Tilts from 2-Groups
Sven Harder, Theodore Jacobson, Zhengdi Sun
2-group global symmetries intertwine 0-form and 1-form symmetries in an interesting way. We analyze universal constraints on lines which are charged under the 1-form subgroup of a…
Intrinsic NISPT Phases, igNISPT Phases, and Mixed Anomalies of Non-Invertible Symmetries
Da-Chuan Lu, Zhengdi Sun
A bosonic non-invertible Symmetry Protected Topological (NISPT) phase in (1+1)-dim is referred to as if it cannot be mapped, under discrete gauging, to a gappe…
Higher structure of non-invertible symmetries from Lagrangian descriptions
Seolhwa Kim, Orr Sela, Zhengdi Sun
The symmetry structure of a quantum field theory is determined not only by the topological defects that implement the symmetry and their fusion rules, but also by the topological n…
Codimension one defects in free scalar field theory
Seolhwa Kim, Per Kraus, Zhengdi Sun
We study various aspects of codimension one defects in free scalar field theory, with particular emphasis on line defects in two-dimensions. These defects are generically non-confo…
SymSETs and self-dualities under gauging non-invertible symmetries
Da-Chuan Lu, Zhengdi Sun, Zipei Zhang
The self-duality defects under discrete gauging in a categorical symmetry can be classified by inequivalent ways of enriching the bulk SymTFT of with $\…
Realizing triality and -ality by lattice twisted gauging in (1+1)d quantum spin systems
Da-Chuan Lu, Zhengdi Sun, Yi-Zhuang You
In this paper, we study the twisted gauging on the (1+1)d lattice and construct various non-local mappings on the lattice operators. To be specific, we define the twisted Gauss law…
Exploring -ality defects in 2-dim QFTs
Da-Chuan Lu, Zhengdi Sun, Zipei Zhang
The Tambara-Yamagami (TY) fusion category symmetry describes the enhanced non-invertible self-duality symmetry of a -dim QFT under gauging a finite A…
A SymTFT for Continuous Symmetries
T. Daniel Brennan, Zhengdi Sun
Symmetry is a powerful tool for studying dynamics in QFT: it provides selection rules, constrains RG flows, and often simplifies analysis. Currently, our understanding is that the…
Self-duality under gauging a non-invertible symmetry
Yichul Choi, Da-Chuan Lu, Zhengdi Sun
We discuss two-dimensional conformal field theories (CFTs) which are invariant under gauging a non-invertible global symmetry. At every point on the orbifold branch of CFTs,…
-deformed free energy of the Airy model
Stephen Ebert, Hao-Yu Sun, Zhengdi Sun
Sharpening the holographic correspondence of Jackiw-Teitelboim (JT) gravity and its dual matrix model description at a finite radial cutoff through the deformat…
deformation in SCFTs and integrable supersymmetric theories
Stephen Ebert, Hao-Yu Sun, Zhengdi Sun
We calculate the -multiplets for two-dimensional Euclidean and superconformal field theories under the deform…
