Higher categorical symmetries and gauging in two-dimensional spin systems
Clement Delcamp, Apoorv Tiwari
We present a framework to systematically investigate higher categorical symmetries in two-dimensional spin systems. Though exotic, such generalised symmetries have been shown to na…
Non-Invertible Symmetry Webs
Lakshya Bhardwaj, Lea E. Bottini, Sakura Schafer-Nameki +1
Non-invertible symmetries have by now seen numerous constructions in higher dimensional Quantum Field Theories (QFT). In this paper we provide an in depth study of gauging 0-form s…
Unifying Constructions of Non-Invertible Symmetries
Lakshya Bhardwaj, Sakura Schafer-Nameki, Apoorv Tiwari
In the past year several constructions of non-invertible symmetries in Quantum Field Theory in have appeared. In this paper we provide a unified perspective on these cons…
Non-Invertible Higher-Categorical Symmetries
Lakshya Bhardwaj, Lea E. Bottini, Sakura Schafer-Nameki +1
We sketch a procedure to capture general non-invertible symmetries of a d-dimensional quantum field theory in the data of a higher-category, which captures the local properties of…
On 2-form gauge models of topological phases
Clement Delcamp, Apoorv Tiwari
We explore various aspects of 2-form topological gauge theories in (3+1)d. These theories can be constructed as sigma models with target space the second classifying space o…
Log-rise of the Resistivity in the Holographic Kondo Model
Bikash Padhi, Apoorv Tiwari, Chandan Setty +1
We study a single-channel Kondo effect using a recently developed holographic large- technique. In order to obtain resistivity of this model, we introduce a probe field. The gra…
Wilson operator algebras and ground states for coupled BF theories
Apoorv Tiwari, Xiao Chen, Shinsei Ryu
The multi-flavor theories in (3+1) dimensions with cubic or quartic coupling are the simplest topological quantum field theories that can describe fractional braiding statisti…
