Emergent higher-form symmetry from type IIB superstring theory
Naoto Kan, Masashi Kawahira, Hiroki Wada
We investigate a higher-form symmetry in type IIB superstring theory, which possesses an symmetry. From the point of view of the low-energy effective field…
Symmetry fractionalization and duality defects in Maxwell theory
Naoto Kan, Kohki Kawabata, Hiroki Wada
We consider Maxwell theory on a non-spin manifold. Depending on the choice of statistics for line operators, there are three non-anomalous theories and one anomalous theory with di…
A lattice regularization of Weyl fermions in a gravitational background
Shoto Aoki, Hidenori Fukaya, Naoto Kan
We report on a lattice fermion formulation with a curved domain-wall mass term to nonperturbatively describe fermions in a gravitational background. In our previous work in 2022, w…
A lattice formulation of Weyl fermions on a single curved surface
Shoto Aoki, Hidenori Fukaya, Naoto Kan
In the standard lattice domain-wall fermion formulation, one needs two flat domain-walls where both of the left- and right-handed massless modes appear. In this work we investigate…
A Microscopic study of Magnetic monopoles in Topological Insulators
Shoto Aoki, Hidenori Fukaya, Naoto Kan +2
In this article, we analyze a magnetic monopole in topological insulators. The monopole obtain a fractional electric charge because of the Witten effect. We consider this system wi…
Higher-group symmetry in lattice gauge theories with restricted topological sectors
Motokazu Abe, Naoto Kan, Okuto Morikawa +3
In this paper, we give a brief overview of generalized symmetries from the point of view of the lattice regularization as a fully regularized framework. At first, we illustrate the…
Why magnetic monopole becomes dyon in topological insulators
Shoto Aoki, Hidenori Fukaya, Naoto Kan +2
The Witten effect predicts that a magnetic monopole acquires a fractional electric charge inside topological insulators. In this work, we give a microscopic description of this phe…
Higher-group structure in lattice Abelian gauge theory under instanton-sum modification
Naoto Kan, Okuto Morikawa, Yuta Nagoya +1
We consider the gauge theory on a four-dimensional torus, where the instanton number is restricted to an integral multiple of . This theory possesses the nontrivial highe…
Effective field theory in light of relative entropy
Qing-Hong Cao, Naoto Kan, Daiki Ueda
We study constraints on the effective field theory (EFT) from the relative entropy between two theories: we refer to these as target and reference theories. The consequence of the…
Violation of bound on chaos for charged probe in Kerr-Newman-AdS black hole
Bogeun Gwak, Naoto Kan, Bum-Hoon Lee +1
We investigate the conjectured bound on the Lyapunov exponent for a charged particle with angular motion in the Kerr-Newman-AdS black hole. The Lyapunov exponent is calculated base…
Bound on the Lyapunov exponent in Kerr-Newman black holes via a charged particle
Naoto Kan, Bogeun Gwak
We investigate the conjecture on the upper bound of the Lyapunov exponent for the chaotic motion of a charged particle around a Kerr-Newman black hole. The Lyapunov exponent is clo…
Half-hypermultiplets and incomplete/complete resolutions in F-theory
Naoto Kan, Shun'ya Mizoguchi, Taro Tani
We consider resolutions of codimension-two enhanced singularities from to and from to in six-dimensional F-theory, where a half-hypermultiplet arises for…
More on a dessin on the base: Kodaira exceptional fibers and mutually (non-)local branes
Shin Fukuchi, Naoto Kan, Rinto Kuramochi +2
A "dessin d'enfant" is a graph embedded on a two-dimensional oriented surface named by Grothendieck. Recently we have developed a new way to keep track of non-localness among 7-bra…
From 3d dualities to hadron physics
Naoto Kan, Ryuichiro Kitano, Shimon Yankielowicz +1
When one of the space-time dimension is compactified on , the QCD exhibits the chiral phase transition at some critical radius. When we further turn on a background term w…
A dessin on the base: a description of mutually non-local 7-branes without using branch cuts
Shin Fukuchi, Naoto Kan, Shun'ya Mizoguchi +1
We consider the special roles of the zero loci of the Weierstrass invariants , in F-theory on an elliptic fibration over or a further fibration thereof…
On Dimensional Reduction of Magical Supergravity Theories
Naoto Kan, Shun'ya Mizoguchi
We prove, by a direct dimensional reduction and an explicit construction of the group manifold, that the nonlinear sigma model of the dimensionally reduced three-dimensional A = R…
