Anomaly Matching Across Dimensions and Supersymmetric Cardy Formulae
Kantaro Ohmori, Luigi Tizzano
't Hooft anomalies are known to induce specific contributions to the effective action at finite temperature. We present a general method to directly calculate such contributions fr…
Kramers-Wannier-like duality defects in (3+1)d gauge theories
Justin Kaidi, Kantaro Ohmori, Yunqin Zheng
We introduce a class of non-invertible topological defects in (3+1)d gauge theories whose fusion rules are the higher-dimensional analogs of those of the Kramers-Wannier defect in…
Numerical evidence for a Haagerup conformal field theory
Tzu-Chen Huang, Ying-Hsuan Lin, Kantaro Ohmori +2
We numerically study an anyon chain based on the Haagerup fusion category, and find evidence that it leads in the long-distance limit to a conformal field theory whose central char…
Matching higher symmetries across Intriligator-Seiberg duality
Yasunori Lee, Kantaro Ohmori, Yuji Tachikawa
We study higher symmetries and anomalies of 4d gauge theory with flavors. We find that they depend on the parity of and , the global form of…
Higher central charges and topological boundaries in 2+1-dimensional TQFTs
Justin Kaidi, Zohar Komargodski, Kantaro Ohmori +2
A 2+1-dimensional topological quantum field theory (TQFT) may or may not admit topological (gapped) boundary conditions. A famous necessary, but not sufficient, condition for the e…
6d/5d exceptional gauge theories from web diagrams
Hirotaka Hayashi, Hee-Cheol Kim, Kantaro Ohmori
We construct novel web diagrams with a trivalent or quadrivalent gluing for various 6d/5d theories from certain Higgsings of 6d conformal matter theories on a circle. The theories…
Replica Instantons from Axion-like Coupling
Kantaro Ohmori
We find a phenomenon in a non-gravitational gauge theory analogous to the replica wormhole in a quantum gravity theory. We consider a reservoir of a scalar field coupled with a gau…
