First-principles design of the spinel iridate Ir2O4 for high-temperature quantum spin ice
Shigeki Onoda, Fumiyuki Ishii
Insulating magnetic rare-earth pyrochlores related to spin ice host emergent bosonic monopolar spinons, which obey a magnetic analogue of quantum electrodynamics and may open a rou…
Scale genesis and gravitational wave in a classically scale invariant extension of the standard model
Jisuke Kubo, Masatoshi Yamada
We assume that the origin of the electroweak (EW) scale is a gauge-invariant scalar-bilinear condensation in a strongly interacting non-abelian gauge sector, which is connected to…
Remarks on the Rellich inequality
Shuji Machihara, Tohru Ozawa, Hidemitsu Wadade
We study the Rellich inequalities in the framework of equalities. We present equalities which imply the Rellich inequalities by dropping remainders. This provides a simple and dire…
Automatic Detection of Omega Signals Captured by the Poynting Flux Analyzer (PFX) on Board the Akebono Satellite
I Made Agus Dwi Suarjaya, Yoshiya Kasahara, Yoshitaka Goto
The Akebono satellite was launched in 1989 to observe the Earth's magnetosphere and plasmasphere. Omega was a navigation system with 8 ground stations transmitter and had transmiss…
Implications of Two-component Dark Matter Induced by Forbidden Channels and Thermal Freeze-out
Mayumi Aoki, Takashi Toma
We consider a model of two-component dark matter based on a hidden symmetry, in which relic densities of the dark matter are determined by forbidden channels and thermal f…
Cosmological model from the holographic equipartition law with a modified Rényi entropy
Nobuyoshi Komatsu
Cosmological equations were recently derived by Padmanabhan from the expansion of cosmic space due to the difference between the degrees of freedom on the surface and in the bulk i…
Ergodicity breaking and Localization of the Nicolai supersymmetric fermion lattice model
Hajime Moriya
We investigate dynamics of the supersymmetric fermion lattice model defined by Hermann Nicolai. We provide its local fermionic constants of motion that exist infinitely many. These…
First-principles Study of Rashba Effect in Ultra-thin Bismuth Surface Alloys
Naoya Yamaguchi, Hiroki Kotaka, Fumiyuki Ishii
We performed density functional calculations for ultra-thin bismuth surface alloys: surface alloys of bismuth and face-centered cubic metals Bi/(111)-$(\sqrt{3}\times\sqrt{3})R3…
Asymptotic analysis of boundary layers in a repulsive particle system
Cameron Hall, Thomas Hudson, Patrick van Meurs
This paper studies the boundary behaviour at mechanical equilibrium at the ends of a finite interval of a class of systems of interacting particles with monotone decreasing repulsi…
Development of wide-field low-energy X-ray imaging detectors for HiZ-GUNDAM
Kazuki Yoshida, Daisuke Yonetoku, Tatsuya Sawano +9
We are planning a future gamma-ray burst (GRB) mission HiZ-GUNDAM to probe the early universe beyond the redshift of z > 7. Now we are developing a small prototype model of wide-fi…
The Quiescent Intracluster Medium in the Core of the Perseus Cluster
Hitomi Collaboration, Felix Aharonian, Hiroki Akamatsu +213
Clusters of galaxies are the most massive gravitationally-bound objects in the Universe and are still forming. They are thus important probes of cosmological parameters and a host…
Inductive intrinsic localized modes in a 1D nonlinear electric transmission line
M. Sato, T. Mukaide, T. Nakaguchi +1
The experimental properties of intrinsic localized modes (ILM) have long been compared with theoretical dynamical lattice models that make use of nonlinear onsite and/or nearest ne…
Initial Experiments on Learning-Based Randomized Bin-Picking Allowing Finger Contact with Neighboring Objects
Kensuke Harada, Weiwei Wan, Tokuo Tsuji +3
This paper proposes a novel method for randomized bin-picking based on learning. When a two-fingered gripper tries to pick an object from the pile, a finger often contacts a neighb…
Testing neutrino mass generation mechanisms from the lepton flavor violating decay of the Higgs boson
Mayumi Aoki, Shinya Kanemura, Kodai Sakurai +1
We investigate how observations of the lepton flavor violating decay of the Higgs boson () can narrow down models of neutrino mass generation mechanisms, whi…
Hitomi constraints on the 3.5 keV line in the Perseus galaxy cluster
Hitomi Collaboration, Felix A. Aharonian, Hiroki Akamatsu +215
High-resolution X-ray spectroscopy with Hitomi was expected to resolve the origin of the faint unidentified E=3.5 keV emission line reported in several low-resolution studies of va…
Characterization of parabolic Hardy spaces by Littlewood-Paley functions
Shuichi Sato
We consider Littlewood-Paley functions associated with non-isotropic dilations. We prove that they can be used to characterize the parabolic Hardy spaces of Calderón-Torchinsky.
Prospects for charged Higgs searches at the LHC
A. G. Akeroyd, M. Aoki, A. Arhrib +25
The goal of this report is to summarize the current situation and discuss possible search strategies for charged scalars, in non-supersymmetric extensions of the Standard Model at…
Leptogenesis in a neutrino mass model coupled with inflaton
Daijiro Suematsu
We propose a scenario for the generation of baryon number asymmetry based on the inflaton decay in a radiative neutrino mass model extended with singlet scalars. In this scenario,…
Remarks on the Gauss images of complete minimal surfaces in Euclidean four-space
Reiko Aiyama, Kazuo Akutagawa, Satoru Imagawa +1
We perform a systematic study of the image of the Gauss map for complete minimal surfaces in Euclidean four-space. In particular, we give a geometric interpretation of the maximal…
NMR Tracing of Hyperfine-Mediated Nuclear Spin Diffusion in Fractional Quantum Hall Domain Phases
S. Miyamoto, T. Hatano, S. Watanabe +1
We present an enhanced diffusion of nuclear spin polarization in fractional quantum Hall domain phases at . Resistively-detected NMR mediated by electrically driven domain-…
Amplitude dependence of image quality in atomically-resolved bimodal atomic microscopy
Hiroaki Ooe, Dominik Kirpal, Daniel S. Wastl +3
In bimodal FM-AFM, two flexural modes are excited simultaneously. The total vertical oscillation deflection range of the tip is the sum of the peak-to-peak amplitudes of both flexu…
Critical endline of the finite temperature phase transition for 2+1 flavor QCD around the SU(3)-flavor symmetric point
Yoshinobu Kuramashi, Yoshifumi Nakamura, Shinji Takeda +1
We investigate the critical endline of the finite temperature phase transition of QCD around the SU(3)-flavor symmetric point at zero chemical potential. We employ the renormalizat…
Baryogenesis in false vacuum
Yuta Hamada, Masatoshi Yamada
The null result in the LHC may indicate that the standard model is not drastically modified up to very high scales such as the GUT/string scale. Having this in the mind, we suggest…
