Spontaneous Distortion and Ferromagnetism Induced by Quantum-well States in Pd(100) Ultrathin Films
Shunsuke Sakuragi, Hiroo Tajiri, Hiroyuki Kageshima +1
We study the crystal structure of Pd(100) ultrathin films, which show ferromagnetism induced by the quantum confinement effect, using in-situ X-ray crystal truncation rod measureme…
Discontinuous change of shear modulus for frictional jammed granular materials
Michio Otsuki, Hisao Hayakawa
The shear modulus of jammed frictional granular materials with the harmonic repulsive interaction under an oscillatory shear is numerically investigated. It is confirmed that the s…
Analysis of Dalitz decays with intrinsic parity violating interactions in resonance chiral perturbation theory
Daiji Kimura, Takuya Morozumi, Hiroyuki Umeeda
Observables of light hadron decays are analyzed in a model of chiral Lagrangian which includes resonance fields of vector mesons. In particular, transition form factors are investi…
Proton Decay Prediction in 5D Gauge-Higgs Unification
Naoyuki Haba, Nobuchika Okada, Toshifumi Yamada
The Higgs boson mass and top quark mass imply that the Higgs quartic coupling vanishes around the scale of GeV, depending on the precise value of the top quark mas…
Naturalness and lepton number/flavor violation in inverse seesaw models
Naoyuki Haba, Hiroyuki Ishida, Yuya Yamaguchi
We introduce three right-handed neutrinos and three sterile neutrinos, and consider an inverse seesaw mechanism for neutrino mass generation. From naturalness point of view, their…
Conjugate boundary condition, hidden particles, and gauge-Higgs inflation
Yugo Abe, Yuhei Goto, Yoshiharu Kawamura +1
We propose an idea that hidden particles can be separated according to gauge quantum numbers from the visible ones by the difference of boundary conditions on extra dimensions. We…
Multiple-point principle with a scalar singlet extension of the Standard Model
Naoyuki Haba, Hiroyuki Ishida, Nobuchika Okada +1
We suggest a scalar singlet extension of the standard model, in which the multiple-point principle (MPP) condition of a vanishing Higgs potential at the Planck scale is realized. A…
On neutrinoless double beta decay in the MSM
Takehiko Asaka, Shintaro Eijima, Hiroyuki Ishida
We consider the neutrinoless double beta () decay in the so-called MSM, in which three right-handed neutrinos with masses below the electroweak scale are additionally intr…
Parametric set-wise injective maps
Eiichi Matsuhashi, Vesko Valov
We introduce the notion of set-wise injective maps and provide results about fiber embeddings. Our results improve some previous results in this area.
Higher order generalization of Fukaya's Morse homotopy invariant of 3-manifolds II. Invariants of 3-manifolds with
Tadayuki Watanabe
In this paper, it is explained that a topological invariant for 3-manifold with can be constructed by applying Fukaya's Morse homotopy theoretic approach for Chern--…
Invisible Axion-Like Dark Matter from Electroweak Bosonic Seesaw
Hiroyuki Ishida, Shinya Matsuzaki, Yuya Yamaguchi
We explore a model based on the classically-scale invariant standard model (SM) with a strongly coupled vector-like dynamics, which is called hypercolor (HC). The scale symmetry is…
Calculation of displacement correlation tensor indicating vortical cooperative motion in two-dimensional colloidal liquids
T. Ooshida, S. Goto, T. Matsumoto +1
As an indicator of cooperative motion in a system of Brownian particles that models two-dimensional colloidal liquids, displacement correlation tensor is calculated analytically an…
Pointwise Hölder Exponents of the Complex Analogues of the Takagi Function in Random Complex Dynamics
Johannes Jaerisch, Hiroki Sumi
We investigate the Hölder regularity of the function of the probability of tending to one minimal set, the partial derivatives of with respect to the probability parameters…
Dark energy from gravitational corrections
Yugo Abe, Masaatsu Horikoshi, Yoshiharu Kawamura
We study physics concerning the cosmological constant problem in the framework of effective field theory and suggest that a dominant part of dark energy can originate from gravitat…
Zero-Suppressed Computation: A New Computation Inspired by ZDDs
Hiroki Morizumi
Zero-suppressed binary decision diagrams (ZDDs) are a data structure representing Boolean functions, and one of the most successful variants of binary decision diagrams (BDDs). On…
A White Paper on keV Sterile Neutrino Dark Matter
R. Adhikari, M. Agostini, N. Anh Ky +133
We present a comprehensive review of keV-scale sterile neutrino Dark Matter, collecting views and insights from all disciplines involved - cosmology, astrophysics, nuclear, and par…
Vacuum stability and naturalness in type-II seesaw
Naoyuki Haba, Hiroyuki Ishida, Nobuchika Okada +1
We study the vacuum stability and perturbativity conditions in the minimal type-II seesaw model. These conditions give characteristic constraints to model parameters. In the model,…
