Dynamics of impurity attraction and repulsion of an intrinsic localized mode in a driven 1-D cantilever array
M. Sato, Y. Sada, W. Shi +6
Both low frequency and high frequency impurity modes have been produced in a SiN micromechanical cantilever array by illumination with either an infrared or visible laser. When suc…
Possible origin of nonlinear magnetic anisotropy variation in electric field effect in a double interface system
Daiki Yoshikawa, Masao Obata, Yusaku Taguchi +2
We investigated the effect of an electric field on the interface magnetic anisotropy of a thin MgO/Fe/MgO layer using density functional theory. The perpendicular magnetic anisotro…
ASTRO-H White Paper - Chemical Evolution in High-z Universe
M. S. Tashiro, D. Yonetoku, M. Ohno +7
In this paper, we demonstrate ASTRO-H's capability to measure the chemical evolution in the high-z (z <~ 3) universe by observing X-ray afterglows of gamma-ray bursts (GRBs) and di…
ASTRO-H White Paper - High Resolution Spectroscopy of Interstellar and Circumgalactic Gas in the Milky Way and Other Galaxies
F. Paerels, N. Yamasaki, N. Anabuki +23
We describe the potential of high resolution imaging spectroscopy with the SXS on ASTRO-H to advance our understanding of the interstellar- and circumgalactic media of our own Gala…
Critical endpoint of finite temperature phase transition for three flavor QCD
Xiao-Yong Jin, Yoshinobu Kuramashi, Yoshifumi Nakamura +2
We investigate the critical endpoint of finite temperature phase transition of QCD at zero chemical potential. We employ the renormalization-group improved Iwasaki gauge ac…
Critical end point of Nf=3 QCD at finite temperature and density
Shinji Takeda, Xiao-Yong Jin, Yoshinobu Kuramashi +2
We investigate the phase structure of 3-flavor QCD in the presence of finite quark chemical potential by using the Wilson-Clover fermion action. Especially, we focus on lo…
Fluctuation Analysis of Time-Averaged Mean-Square Displacement for Langevin Equation with Time-Dependent and Fluctuating Diffusivity
Takashi Uneyama, Tomoshige Miyaguchi, Takuma Akimoto
The mean-square displacement (MSD) is widely utilized to study the dynamical properties of stochastic processes. The time-averaged MSD (TAMSD) provides some information on the dyna…
Embedded area-constrained Willmore tori of small area in Riemannian three-manifolds II: Morse Theory
Norihisa Ikoma, Andrea Malchiodi, Andrea Mondino
This is the second of a series of two papers where we construct embedded Willmore tori with small area constraint in Riemannian three-manifolds. In both papers the construction rel…
Embedded area-constrained Willmore tori of small area in Riemannian three-manifolds I: Minimization
Norihisa Ikoma, Andrea Malchiodi, Andrea Mondino
We construct embedded Willmore tori with small area constraint in Riemannian three-manifolds under some curvature condition used to prevent Möbius degeneration. The construction re…
Self-Consistent Field Model Simulations for Statistics of Amorphous Polymer Chains in Crystalline Lamellar Structures
Takashi Uneyama, Takafumi Miyata, Koh-hei Nitta
We calculate statistical properties of amorphous polymer chains between crystalline lamellae by self-consistent field model simulations. In our model, an amorphous subchain is mode…
Efficient optical path folding by using multiple total internal reflections in a microcavity
Susumu Shinohara, Satoshi Sunada, Takehiro Fukushima +3
We propose using an asymmetric resonant microcavity for the efficient generation of an optical path that is much longer than the diameter of the cavity. The path is formed along a…
Atomistic mechanism of perfect alignment of nitrogen-vacancy centers in diamond
Takehide Miyazaki, Yoshiyuki Miyamoto, Toshiharu Makino +7
Nitrogen-vacancy (NV) centers in diamond have attracted a great deal of attention because of their possible use in information processing and electromagnetic sensing technologies.…
Inflation in a modified radiative seesaw model
Romy H. S. Budhi, Shoichi Kashiwase, Daijiro Suematsu
The existence of the inflationary era in the early Universe seems to be strongly supported by recent CMB observations. However, only a few realistic inflation scenarios which have…
Lectures on BCOV holomorphic anomaly equations
Atsushi Kanazawa, Jie Zhou
The present article surveys some mathematical aspects of the BCOV holomorphic anomaly equations introduced by Bershadsky, Cecotti, Ooguri and Vafa. It grew from a series of lecture…
Entropic cosmology in a dissipative universe
Nobuyoshi Komatsu, Shigeo Kimura
The bulk viscosity of cosmological fluid and the creation of cold dark matter both result in the generation of irreversible entropy (related to dissipative processes) in a homogene…
Multicomponent Dark Matter in Radiative Seesaw Model and Monochromatic Neutrino Flux
Mayumi Aoki, Jisuke Kubo, Hiroshi Takano
We consider a two loop radiative seesaw model with an exact symmetry, which can stabilize two or three dark matter particles. The model is a simple extension of t…
