Holographic QCD Matter: Chiral Soliton Lattices in Strong Magnetic Field
Markus A. G. Amano, Minoru Eto, Muneto Nitta +1
We investigate the chiral soliton lattice (CSL) in the framework of holographic QCD in magnetic field. Under appropriate boundary conditions for the gauge field and the quark mass…
Stochastic gravitational wave background anisotropies from inflation with non-Bunch-Davies states
Shingo Akama, Shin'ichi Hirano, Shuichiro Yokoyama
It is known that stochastic gravitational wave backgrounds (SGWBs) have anisotropies generated by squeezed-type tensor non-Gaussianities originating from scalar-tensor-tensor (STT)…
Parametrized Black Hole Quasinormal Ringdown Formalism for Higher Overtones
Shin'ichi Hirano, Masashi Kimura, Masahide Yamaguchi +1
We investigate the parametrized black hole quasinormal ringdown formalism, which is a robust framework used to analyze quasinormal modes in systems that closely resemble general re…
Gauge-independent transition separating confinement and Higgs phases in lattice SU(2) gauge theory with a scalar field in the fundamental representation
Ryu Ikeda, Seikou Kato, Kei-Ichi Kondo +1
According to the preceding studies, the lattice SU(2) gauge-scalar model with a single scalar field in the fundamental representation of the gauge group has a single confinement-Hi…
First test of the consistency relation for the large-scale structure using the anisotropic three-point correlation function of BOSS DR12 galaxies (An explanatory video is available at https://youtu.be/Zi36ooLPhss.)
Naonori S. Sugiyama, Daisuke Yamauchi, Tsutomu Kobayashi +6
We present, for the first time, an observational test of the consistency relation for the large-scale structure (LSS) of the Universe through a joint analysis of the anisotropic tw…

Norio Konno, Iwao Sato, Etsuo Segawa +1
We consider a spectral analysis on the quantum walks on graph with the local coin operators and the flip flop shift. The quantum coin operators have co…
Double-winding Wilson loops in SU(N) lattice Yang-Mills gauge theory
Seikou Kato, Akihiro Shibata, Kei-Ichi Kondo
We study double-winding Wilson loops in lattice Yang-Mills gauge theory by using both strong coupling expansions and numerical simulations. First, we examine how the area l…
The limit theorem with respect to the matrices on non-backtracking paths of a graph
Takehiro Hasegawa, Takashi Komatsu, Norio Konno +4
We give a limit theorem with respect to the matrices related to non-backtracking paths of a regular graph. The limit obtained closely resembles the th moments of the arcsine law…

Takashi Komatsu, Norio Konno, Iwao Sato
We define a zeta function of a graph by using the time evolution matrix of a general coined quantum walk on it, and give a determinant expression for the zeta function of a finite…
