Intertwining Defects and Fermion-Boundary Scattering from TQFT
Kantaro Ohmori, Masataka Watanabe, Pengcheng Wei +1
We construct conformal boundary conditions of free Dirac fermions that preserve chiral, anomaly-free symmetries, and determine the associated fermion-boundary scattering, using the…
Symmetry Spans and Enforced Gaplessness
Takamasa Ando, Kantaro Ohmori
Anomaly matching for continuous symmetries has been the primary tool for establishing symmetry enforced gaplessness - the phenomenon where global symmetry alone forces a quantum sy…
Higgsing Transitions from Topological Field Theory & Non-Invertible Symmetry in Chern-Simons Matter Theories
Clay Cordova, Diego García-Sepúlveda, Kantaro Ohmori
Non-invertible one-form symmetries are naturally realized in (2+1)d topological quantum field theories. In this work, we consider the potential realization of such symmetries in (2…
Gapless Foliated-Exotic Duality
Kantaro Ohmori, Shutaro Shimamura
In this work, we construct a new foliated quantum field theory equivalent to the exotic -theory -- a fractonic gapless scalar field theory described by tensor gauge fields and e…
Higher Representations and Quark Confinement
Finn Gagliano, Andrea Grigoletto, Kantaro Ohmori
The concept of a (de)confined phase in QFT is well-defined in the presence of -form symmetries and their spontaneous symmetry breaking. However, in scenarios where such symmetri…
Simons Lectures on Categorical Symmetries
Davi Costa, Clay Córdova, Michele Del Zotto +10
Global Categorical Symmetries are a powerful new tool for analyzing quantum field theories. This volume compiles lecture notes from the 2022 and 2023 summer schools on Global Categ…
Emergent Non-Invertible Symmetries Bridging UV and IR Phases -- The Adjoint QCD Example
Michele Del Zotto, Shani Nadir Meynet, Daniele Migliorati +1
In this letter, we demonstrate how an emergent non-invertible symmetry along a renormalization group (RG) flow reveals connections between microscopic and macroscopic physics. We i…
Representation Theory of Solitons
Clay Cordova, Nicholas Holfester, Kantaro Ohmori
Solitons in two-dimensional quantum field theory exhibit patterns of degeneracies and associated selection rules on scattering amplitudes. We develop a representation theory that c…
Chiral Edge States Emerging on Anyon-Net
Atsushi Ueda, Kansei Inamura, Kantaro Ohmori
We propose a symmetry-based approach to constructing lattice models for chiral topological phases, focusing on non-Abelian anyons. Using a 2+1D version of anyon chains and modular…
