Note on a Product Formula Related to Quantum Zeno Dynamics
Pavel Exner, Takashi Ichinose
Given a nonnegative self-adjoint operator acting on a separable Hilbert space and an orthogonal projection such that is densely defined, we…
Electric dipole moments in the extended scotogenic models
Motoko Fujiwara, Junji Hisano, Chihiro Kanai +1
Electric dipole moments (EDMs) of charged leptons arise from a new source of CP violation in the lepton sector. In this paper, we calculate the EDMs of the charged leptons in the m…
Non-thermal Production of PNGB Dark Matter and Inflation
Yoshihiko Abe, Takashi Toma, Koichi Yoshioka
A pseudo Nambu-Goldstone boson (pNGB) is a natural candidate of dark matter in that it avoids the severe direct detection bounds. We show in this paper that the pNGB has another di…
Physical deep learning based on optimal control of dynamical systems
Genki Furuhata, Tomoaki Niiyama, Satoshi Sunada
Deep learning is the backbone of artificial intelligence technologies, and it can be regarded as a kind of multilayer feedforward neural network. An essence of deep learning is inf…
Geometrical Characterization of Glass Nanopipettes with Sub-10 nm Pore Diameter by Transmission Electron Microscopy
Kazuki Shigyou, Linhao Sun, Riku Yajima +9
Glass nanopipettes are widely used for various applications in nanosciences. In most of the applications, it is important to characterize their geometrical parameters, such as the…
Anomalous transport due to Weyl fermions in the chiral antiferromagnets Mn, = Sn, Ge
Taishi Chen, Takahiro Tomita, Susumu Minami +9
The recent discoveries of strikingly large zero-field Hall and Nernst effects in antiferromagnets Mn, ( = Sn, Ge) have brought the study of magnetic topological states to…
Evolution of dissipative and non-dissipative universes in holographic cosmological models with a power-law term
Nobuyoshi Komatsu
Density perturbations related to structure formations are expected to be different in dissipative and non-dissipative universes, even if the background evolution of the two univers…
Low scale leptogenesis in a model with promising structure
Daijiro Suematsu
We consider a simple extension of the standard model, which could give a solution to its issues through both the Peccei-Quinn mechanism and the Nelson-Barr mechanism. Its low…
Results in estimates for -plane transforms
Shuichi Sato
This is an expository paper. We give proofs of some results of M. Christ (1984) and S. W. Drury (1984) for -plane transforms. Also, we give proofs for some related results inclu…
Electronic and magnetic characterization of epitaxial CrBr monolayers
Shawulienu Kezilebieke, Orlando J. Silveira, Md N. Huda +8
The ability to imprint a given material property to another through proximity effect in layered two-dimensional materials has opened the way to the creation of designer materials.…
On distributional and asymptotic results for exponential functional of renewal -- reward processes describing risk models
J. Akahori, C. Constantinescu, Y. Imamura +1
Inspired by the double-debt problem in Japan where the mortgagor has to pay the remaining loan even if their house was destroyed by a catastrophic event, we model the lender's cash…
Inflation and DM phenomenology in a scotogenic model extended with a real singlet scalar
Tsuyoshi Hashimoto, Daijiro Suematsu
We study an extension of the scotogenic model with a real singlet scalar. It gives an origin of the mass of right-handed neutrinos and plays a role of inflaton through a non-minima…
Conformation of ultra-long-chain fatty acid in lipid bilayer: Molecular dynamics study
Kazutomo Kawaguchi, Koh M. Nakagawa, Satoshi Nakagawa +3
Ultra-long-chain fatty acids (ULCFAs) are biosynthesized in the restricted tissues such as retina, testis, and skin. The conformation of a single ULCFA, in which the sn-1 unsaturat…
A hybrid seesaw model and hierarchical neutrino flavor structures based on symmetry
Mayumi Aoki, Daiki Kaneko
We propose a hybrid seesaw model based on flavor symmetry, which generates a large hierarchical flavor structure. In our model, tree-level and one-loop seesaw mechanisms pr…
Primordial gravitational waves in a minimal model of particle physics and cosmology
Andreas Ringwald, Ken'ichi Saikawa, Carlos Tamarit
In this paper we analyze the spectrum of the primordial gravitational waves (GWs) predicted in the Standard Model*Axion*Seesaw*Higgs portal inflation (SMASH) model, which was propo…
Enhancement of transverse thermoelectric conductivity originating from stationary points in nodal line
Susumu Minami, Fumiyuki Ishii, Motoaki Hirayama +3
Motivated by the recent discovery of a large anomalous Nernst effect in CoMnGa, Fe (=Al, Ga) and CoSnS, we performed a first-principles study to clarify the…
Heavy Dark Matter, Neutrino Masses and Higgs Naturalness from a Strongly Interacting Hidden Sector
Mayumi Aoki, Vedran Brdar, Jisuke Kubo
We consider the extension of the Standard Model (SM) with a strongly interacting QCD-like hidden sector, at least two generations of right-handed neutrinos and one scalar singlet.…
The isotropic interplanetary dust cloud and near-infrared extragalactic background light observed with COBE/DIRBE
Kei Sano, Shuji Matsuura, Kazuma Yomo +1
We report observation of isotropic interplanetary dust (IPD) by analyzing the infrared (IR) maps of Diffuse Infrared Background Experiment (DIRBE) onboard the Cosmic Background Exp…
Synthesis and Local Probe Gating of a Monolayer Metal-Organic Framework
Linghao Yan, Orlando J. Silveira, Benjamin Alldritt +3
Achieving large-area uniform two-dimensional (2D) metal-organic frameworks (MOFs) and controlling their electronic properties on inert surfaces is a big step towards future applica…

V. A. Acciari, S. Ansoldi, L. A. Antonelli +301
Long-duration gamma-ray bursts (GRBs) originate from ultra-relativistic jets launched from the collapsing cores of dying massive stars. They are characterised by an initial phase o…
