Resurfacing processes constrained by crater distribution on Ryugu
Naofumi Takaki, Yuichiro Cho, Tomokatsu Morota +16
Understanding the geological modification processes on asteroids can provide information concerning their surface history. Images of small asteroids from spacecraft show a depletio…
Observation of Variations in Cosmic Ray Single Count Rates During Thunderstorms and Implications for Large-Scale Electric Field Changes
R. U. Abbasi, T. Abu-Zayyad, M. Allen +160
We present the first observation by the Telescope Array Surface Detector (TASD) of the effect of thunderstorms on the development of cosmic ray single count rate intensity over a 7…
High-Resolution Observations of Bright Boulders on Asteroid Ryugu: 1. Size Frequency Distribution and Morphology
Chiho Sugimoto, Eri Tatsumi, Yuichiro Cho +34
The near-Earth asteroid (162173) Ryugu displays a Cb-type average spectrum and a very low average normal albedo of 0.04. Although the majority of boulders on Ryugu have reflectance…
High-Resolution Observations of Bright Boulders on Asteroid Ryugu: 2. Spectral Properties
Chiho Sugimoto, Eri Tatsumi, Yuichiro Cho +34
Many small boulders with reflectance values higher than 1.5 times the average reflectance have been found on the near-Earth asteroid 162173 Ryugu. Based on their visible wavelength…
Monopoles of the Dirac type and color confinement in QCD
Tsuneo Suzuki, Atsuki Hiraguchi, Katsuya Ishiguro
We present results of Monte-Carlo studies of a new color confinement scheme proposed recently due to Abelian-like monopoles of the Dirac type corresponding in the continuum…
A reduction of the string bracket to the loop product
Katsuhiko Kuribayashi, Takahito Naito, Shun Wakatsuki +1
The negative cyclic homology for a differential graded algebra over the rational field has a quotient of the Hochschild homology as a direct summand if the -action is trivial. W…
Equation of state of neutron star matter and its warm extension with an interacting hadron resonance gas
Yuki Fujimoto, Kenji Fukushima, Yoshimasa Hidaka +2
We propose an interpolating equation of state that satisfies phenomenologically established boundary conditions in two extreme regimes at high temperature and low baryon density an…
Beta families arising from a self map on
Eva Belmont, Katsumi Shimomura
We show that is a permanent cycle in the 3-primary Adams-Novikov spectral sequence computing , and use this to conclude that the families for…
Dissipation-relaxation dynamics of a spin-1/2 particle with a Rashba-type spin-orbit coupling in an ohmic heat bath
Tomohiro Hata, Eiji Nakano, Kei Iida +2
Spin-orbit coupling (SOC), which is inherent to a Dirac particle that moves under the influence of electromagnetic fields, manifests itself in a variety of physical systems includi…
Three-body crossover from a Cooper triple to bound trimer state in three-component Fermi gases near a triatomic resonance
Hiroyuki Tajima, Shoichiro Tsutsui, Takahiro M. Doi +1
We theoretically investigate ground-state properties of a three-component Fermi gas with pairwise contact interactions between different components near a triatomic resonance where…
Resonant pair-exchange scattering and BCS-BEC crossover in a system composed of dispersive and heavy incipient bands: a Feshbach analogy
Kazunari Ochi, Hiroyuki Tajima, Kei Iida +1
We theoretically show that a two-band system with very different masses harbors a resonant pair scattering that leads to novel pairing properties, as highlighted by the Bardeen-Coo…
Unitary -wave Fermi gas in one dimension
Hiroyuki Tajima, Shoichiro Tsutsui, Takahiro M. Doi +1
We elucidate universal many-body properties of a one-dimensional, two-component ultracold Fermi gas near the -wave Feshbach resonance. The low-energy scattering in this system c…
Binding two and three particles in cold neutron matter
H. Moriya, H. Tajima, W. Horiuchi +2
We elucidate the fate of neighboring two and three- particles in cold neutron matter by focusing on an analogy between such systems and Fermi polarons realized in ultracold…
Coulomb screening effect on the Hoyle state energy in thermal plasmas
Lai Hnin Phyu, H. Moriya, W. Horiuchi +3
The first excited state of C, the so-called Hoyle state, plays an essential role in a triple- (He) reaction, which is a main contributor to the synthesis of…
Optical spin conductivity in ultracold quantum gases
Yuta Sekino, Hiroyuki Tajima, Shun Uchino
We show that the optical spin conductivity being a small AC response of a bulk spin current and elusive in condensed matter systems can be measured in ultracold atoms. We demonstra…
Condensation of Cooper Triples
Sora Akagami, Hiroyuki Tajima, Kei Iida
The condensation of Cooper pairs, originating from the Fermi-surface instability due to a weakly attractive interaction between two fermions, opened a new frontier for exploring ma…
Polaron Problems in Ultracold Atoms: Role of a Fermi Sea across Different Spatial Dimensions and Quantum Fluctuations of a Bose Medium
Hiroyuki Tajima, Junichi Takahashi, Simeon I. Mistakidis +2
The notion of a polaron, originally introduced in the context of electrons in ionic lattices, helps us to understand how a quantum impurity behaves when being immersed in and inter…
