Protected operators in non-local defect CFTs from AdS
Jiaxin Qiao
For a local quantum field theory in anti-de Sitter space with conformal boundary conditions but without dynamical gravity, the boundary theory is generically a non-local conformal…
Yang-Mills Flux Tube in AdS
Barak Gabai, Victor Gorbenko, Jiaxin Qiao
We initiate the study of flux tubes in confining gauge theories placed in a rigid AdS background, which serves as an infrared regulator. Varying the AdS radius from large to small…
Quantum Groups as Global Symmetries II. Coulomb Gas Construction
Barak Gabai, Victor Gorbenko, Jiaxin Qiao +2
We study a conformal field theory that arises in the infinite-volume limit of a spin chain with global symmetry. Most operators in the theory are defect-ending operator…
Symmetry-deformed toric codes and the quantum dimer model
Jiaxin Qiao, Yoshito Watanabe, Simon Trebst
Motivated by the recent introduction of a -symmetric toric code model, we investigate symmetry-based deformations of topological order by systematically deconstructing the Ga…
Quantum Groups as Global Symmetries
Barak Gabai, Victor Gorbenko, Jiaxin Qiao +2
We study quantum field theories which have quantum groups as global internal symmetries. We show that in such theories operators are generically non-local, and should be thought as…
