Center-twisted Gribov spectra and the finite-volume Gaussian response in the refined Gribov--Zwanziger framework
Okuto Morikawa
We develop a continuum framework for comparing the Gribov--Zwanziger and center-vortex descriptions of confinement through the gauge-invariant twisted partition function of the ele…
Eigenstate Thermalization Hypothesis with projective representation
Soma Onoda, Osamu Fukushima, Ryusuke Hamazaki +1
The Eigenstate Thermalization Hypothesis (ETH) provides a sufficient condition for thermalization of isolated quantum systems. While the standard ETH is formulated in the absence o…
Note on lattice description of generalized symmetries in gauge theories
Motokazu Abe, Okuto Morikawa, Soma Onoda
Topology and generalized symmetries in the gauge theory are considered in the continuum and the lattice. Starting from the gauge theory with the 't~Hoo…
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…
Phase structure of linear quiver gauge theories from anomaly matching
Okuto Morikawa, Hiroki Wada, Satoshi Yamaguchi
We consider the phase structure of the linear quiver gauge theory, using the 't Hooft anomaly matching condition. This theory is characterized by the length of the quiver diagr…
Fractional topological charge in lattice Abelian gauge theory
Motokazu Abe, Okuto Morikawa, Hiroshi Suzuki
We construct a non-trivial principal bundle on~ from the compact lattice gauge field by generalizing Lüscher's constriction so that the cocycle cond…

Masahiro Ashie, Okuto Morikawa, Hiroshi Suzuki +1
We present additional observations to previous studies on the infrared (IR) renormalon in QCD(adj.), the gauge theory with -flavor adjoint Weyl fermions on~$\m…
Identification of perturbative ambiguity canceled against bion
Okuto Morikawa, Hiromasa Takaura
It was conjectured that bions, semi-classical objects found in a compactified spacetime, are responsible for the cancellation of the so-called renormalon ambiguities. Contrary to t…
Vacuum energy of the supersymmetric model on in the expansion
Kosuke Ishikawa, Okuto Morikawa, Kazuya Shibata +1
By employing the expansion, we compute the vacuum energy~ of the two-dimensional supersymmetric (SUSY) model on~ with $\mathb…
Renormalon structure in compactified spacetime
Kosuke Ishikawa, Okuto Morikawa, Kazuya Shibata +2
We point out that the location of renormalon singularities in theory on a circle-compactified spacetime (with a small radius ) can differ fr…
Infrared renormalon in QCD(adj.) on
Masahiro Ashie, Okuto Morikawa, Hiroshi Suzuki +2
We study the infrared renormalon in the gluon condensate in the gauge theory with -flavor adjoint Weyl fermions (QCD(adj.)) on~ with the $\math…
Infrared renormalon in the supersymmetric model on
Kosuke Ishikawa, Okuto Morikawa, Akira Nakayama +3
In the leading order of the large- approximation, we study the renormalon ambiguity in the gluon (or, more appropriately, photon) condensate in the 2D supersymmetric $\mathbb{C}…
Axial anomaly in a gravitational field via the gradient flow
Okuto Morikawa, Hiroshi Suzuki
A regularization-independent universal formula for the energy--momentum tensor in gauge theory in the flat spacetime can be written down by employing the so-called Yang--Mills grad…
Gradient flow and the Wilsonian renormalization group flow
Hiroki Makino, Okuto Morikawa, Hiroshi Suzuki
The gradient flow is the evolution of fields and physical quantities along a dimensionful parameter~, the flow time. We give a simple argument that relates this gradient flow an…
