Measurement of Interstellar Polarization and Estimation of Galactic Extinction for the Direction of X-ray Black Hole Binary V404 Cygni
Ryosuke Itoh, Yasuyuki T. Tanaka, Koji S. Kawabata +12
V404 Cygni is a well-known black hole binary candidate thought to have relativistic jets. It showed extreme outbursts on June 2015, characterized by a large amplitude and short tim…
Analysis of right-handed Majorana neutrino mass in an Pati--Salam model with democratic texture
Masaki J. S. Yang
In this paper, we attempt to build an unified model with democratic texture, that have some unification between and . Since the flavor symmetry…
On the arc-analytic type of some weighted homogeneous polynomials
Jean-Baptiste Campesato
It is known that the weights of a complex weighted homogeneous polynomial with isolated singularity are analytic invariants of . When this resu…
Recommendations and illustrations for the evaluation of photonic random number generators
Joseph D. Hart, Yuta Terashima, Atsushi Uchida +3
The never-ending quest to improve the security of digital information combined with recent improvements in hardware technology has caused the field of random number generation to u…
Hard X-ray Spectral Investigations of Gamma-ray Bursts, 120521C and 130606A, at High-redshift z~6
Tetsuya Yasuda, Yuji Urata, Junich Enomoto +1
This study presents the temporal and spectral analysis of the prompt emission of two high-redshift gamma-ray bursts (GRBs), 120521C at and 130606A at , which we…
Multiferroic magnetic spirals induced by random magnetic exchanges
Andrea Scaramucci, Hiroshi Shinaoka, Maxim V. Mostovoy +4
Multiferroism can originate from the breaking of inversion symmetry caused by magnetic-spiral order. The usual mechanism for stabilizing a magnetic spiral is competition between ma…
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…
Stability of trace theorems on the sphere
Neal Bez, Chris Jeavons, Tohru Ozawa +1
We prove stable versions of trace theorems on the sphere in with optimal constants, thus obtaining rather precise information regarding near-extremisers. We also obtain stabi…
Atomic displacements and lattice distortion in the magnetic-field-induced charge ordered state of SmRuP
T. Matsumura, S. Michimura, T. Inami +5
Structural properties of SmRuP in the anomalous magnetic ordered phase between K and K in magnetic fields has been studied by x-ray dif…
Ground State Phase Diagram of S=1 Diamond Chains
Kazuo Hida, Ken'ichi Takano
We investigate the ground-state phase diagram of a spin-1 diamond chain. Owing to a series of conservation laws, any eigenstate of this system can be expressed using the eigenstate…
Identification of the Lowest , Isobaric Analog State in Co and Its Impact on the Understanding of -Decay Properties of Ni
X. Xu, P. Zhang, P. Shuai +35
Masses of Co were measured for the first time with an accuracy of keV, an unprecedented precision reached for short-lived nuclei in the isochronous mass spect…
Spiral order from orientationally correlated random bonds in classical XY models
Andrea Scaramucci, Hiroshi Shinaoka, Maxim V. Mostovoy +3
We discuss the stability of ferromagnetic long-range order in three-dimensional classical XY ferromagnets upon substitution of a small subset of equally oriented bonds by impurity…
Two Distinct-Absorption X-Ray Components from Type IIn Supernovae: Evidence for Asphericity in the Circumstellar Medium
Satoru Katsuda, Keiichi Maeda, Aya Bamba +7
We present multi-epoch X-ray spectral observations of three Type IIn supernovae (SNe) 2005kd, 2006jd, and 2010jl, acquired with Chandra, XMM-Newton, Suzaku, and Swift. Previous ext…
Progenitors of type Ia supernovae
Keiichi Maeda, Yukikatsu Terada
Natures of progenitors of type Ia Supernovae (SNe Ia) have not yet been clarified. There has been long and intensive discussion on whether the so-called single degenerate (SD) scen…
Continuous-time hybridization expansion quantum impurity solver for multi-orbital systems with complex hybridizations
Hiroshi Shinaoka, Emanuel Gull, Philipp Werner
We describe an open-source implementation of the continuous-time hybridization-expansion quantum Monte Carlo method for impurity models with general instantaneous two-body interact…
Updated Core Libraries of the ALPS Project
A. Gaenko, A. E. Antipov, G. Carcassi +16
The open source ALPS (Algorithms and Libraries for Physics Simulations) project provides a collection of physics libraries and applications, with a focus on simulations of lattice…
Search for EeV Protons of Galactic Origin
R. U. Abbasi, M. Abe, T. Abu-Zayyad +126
Cosmic rays in the energy range - eV are thought to have a light, probably protonic, composition. To study their origin one can search for anisotropy in the…
Topological Phases of Spin-1/2 Ferromagnetic--Antiferromagnetic Alternating Heisenberg Chains with Alternating Next-Nearest-Neighbour Interaction
Kazuo Hida
A series of symmetry-protected topological(SPT) and trivial spin-gap phases in the spin-1/2 ferromagnetic--antiferromagnetic alternating Heisenberg chain with alternating next-near…
A spin-freezing perspective on cuprates
Philipp Werner, Shintaro Hoshino, Hiroshi Shinaoka
The high-temperature superconducting state in cuprates appears if charge carriers are doped into a Mott insulating parent compound. An unresolved puzzle is the unconventional natur…
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…
