Anyon Proliferation and Anyon Superconductivity in Higgsing Transitions via Conformal Embeddings
Diego García-Sepúlveda, Da-Chuan Lu
We discuss (2+1)d Chern-Simons Higgsing transitions based on conformal embeddings and their relation to the proliferation of anyons. These transitions preserve or enlarge the intri…
Self-dual gauge theory in 2+1d: lattice model and topological phase transitions
Da-Chuan Lu, Chong Wang, Ashvin Vishwanath
Electric-magnetic self-duality of the gauge theory, realized microscopically as a half-lattice-translation exchanging electric charge and magnetic flux, has been an…
Sp(4,Z) actions on 3d U(1)^2 symmetric theories: Order-five duality and bilayer quantum Hall hierarchies
Yasin F. Alam, Andreas Karch, Da-Chuan Lu +1
The electromagnetic duality of 4d Maxwell theory induces theory-generating operations on 3d theories with global symmetry. For theories with $U(1…
Spontaneous breaking of non-invertible symmetries and duality to beyond-Landau transitions
Xie Chen, Shang Liu, Da-chuan Lu +1
Spontaneous symmetry breaking is a well-understood mechanism for generating distinct phases of matter. Recently, the notion of symmetry has been broadened to include operations wit…
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…
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…
Optical Conductivity in Symmetric Mass Generation Insulators
Meng Zeng, Fu Xu, Da-Chuan Lu +1
Symmetric mass generation (SMG) insulators are interaction-driven, featureless Mott insulating states in quantum many-body fermionic systems. Recent advancements suggest that zeros…
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,…
