Non-Invertible Froggatt-Nielsen Symmetry
Hajime Otsuka, Ryo Yokokura
We investigate non-invertible completions of anomalous flavor symmetries and their application to Dirac neutrino masses. We formulate symmetry defects dressed by topological quantu…
Testing graph isomorphism using simple quantum circuits
Samuel Beasley, Ashley Montanaro
The graph isomorphism problem asks whether two graphs are equivalent up to a permutation of their vertices. Its precise computational complexity remains unresolved, and it is still…
Non-Abelian vortices in gauge theory and non-invertible symmetries
Yoshihiko Abe, Tetsutaro Higaki, Kazuya Murakami +2
We construct finite-tension non-Abelian vortex solutions in a renormalizable -dimensional gauge theory Higgsed to the tetrahedral group by a Higgs field in the…
Lazarides-Shafi axion models as Dijkgraaf-Witten theories
Motoo Suzuki, Ryo Yokokura
Axion models often face the domain wall problem, which threatens the standard big-bang cosmology. The Lazarides-Shafi mechanism attempts to resolve this by identifying degenerate v…
Selection rules of topological solitons from non-invertible symmetries in axion electrodynamics
Yoshimasa Hidaka, Muneto Nitta, Ryo Yokokura
We investigate a relation between non-invertible symmetries and selection rules of topological solitons such as axionic domain walls and magnetic strings in the -dimensional…
Spin Statistics and Surgeries of Topological Solitons in QCD Matter in Magnetic Field
Yuki Amari, Muneto Nitta, Ryo Yokokura
The ground state of QCD with two flavors (up and down quarks) at finite baryon density in sufficiently strong magnetic field is in a form of either a chiral soliton lattice(CSL), a…
Stringy constraints on primordial electromagnetic fields in axion inflation
Hajime Otsuka, Ryo Yokokura
We study primordial electromagnetic fields in effective actions of string theory. In contrast to a conventional scenario of producing primordial electromagnetic fields induced by t…
Generalized chiral instabilities, linking numbers, and non-invertible symmetries
Naoki Yamamoto, Ryo Yokokura
We demonstrate a universal mechanism of a class of instabilities in infrared regions for massless Abelian -form gauge theories with topological interactions, which we call gener…
Dipole symmetries from the topology of the phase space and the constraints on the low-energy spectrum
Tomas Brauner, Naoki Yamamoto, Ryo Yokokura
We demonstrate the general existence of a local dipole conservation law in bosonic field theory. The scalar charge density arises from the symplectic form of the system, whereas th…

Ryo Yokokura
We study non-invertible global symmetries in -dimensional axion electrodynamics with a massless axion and a massless photon. In addition to a previously known non-invertible…
BCF anomaly and higher-group structure in the low energy effective theories of mesons
Tatsuki Nakajima, Tadakatsu Sakai, Ryo Yokokura
We discuss the BCF anomaly of massless QCD-like theories, first obtained by Anber and Poppitz, from the viewpoint of the low energy effective theories. We assume that the QCD-like…
Higher-group structure in -dimensional axion-electrodynamics
Tatsuki Nakajima, Tadakatsu Sakai, Ryo Yokokura
We investigate -dimensional axion electrodynamics for the purpose of exploring a higher-group structure underlying it. This is manifested as a Green-Schwarz transformation of t…
Unstable Nambu-Goldstone modes
Naoki Yamamoto, Ryo Yokokura
Nambu-Goldstone (NG) modes for 0-form and higher-form symmetries can become unstable in the presence of background fields. Examples include the instability of a photon with a time-…

Mass generation of gauge fields can be universally described by topological couplings in gapped systems, such as the Abelian Higgs model in dimensions and the Maxwell-Chern…
Counting Nambu-Goldstone modes of higher-form global symmetries
Yoshimasa Hidaka, Yuji Hirono, Ryo Yokokura
We discuss the counting of Nambu-Goldstone (NG) modes associated with the spontaneous breaking of higher-form global symmetries. Effective field theories of NG modes are developed…
Higher-form symmetries and 3-group in axion electrodynamics
Yoshimasa Hidaka, Muneto Nitta, Ryo Yokokura
We study higher-form symmetries in a low-energy effective theory of a massless axion coupled with a photon in dimensions. It is shown that the higher-form symmetries of thi…
Emergent discrete 3-form symmetry and domain walls
Yoshimasa Hidaka, Muneto Nitta, Ryo Yokokura
We show that axion models with the domain wall number in dimensions, i.e., periodic scalar field theories admitting axion domain walls, exhibit an emergent ${\mathb…
