Experimentally shock-induced melt veins in basalt: Improving the shock classification of eucrites
Haruka Ono, Kosuke Kurosawa, Takafumi Niihara +15
Basaltic rocks occur widely on the terrestrial planets and differentiated asteroids, including the asteroid 4 Vesta. We conducted a shock recovery experiment with decaying compress…
Density-Induced Hadron-Quark Crossover via the Formation of Cooper Triples
Hiroyuki Tajima, Shoichiro Tsutsui, Takahiro M. Doi +1
We discuss the hadron--quark crossover accompanied by the formation of Cooper triples (three-body counterpart of Cooper pairs) by analogy with the Bose--Einstein condensate to Bard…
Probing the hadron mass spectrum in dense two-color QCD with the linear sigma model
Daiki Suenaga, Kotaro Murakami, Etsuko Itou +1
We investigate modifications of hadron masses at finite quark chemical potential in two-flavor and two-color QCD, of which the data are available from lattice simulations, within a…
On products of beta and gamma elements in the homotpy of the first Smith-Toda spectrum
Katsumi Shimomura, Mao-No-Suke Shimomura
In this paper, we determine the first cohomology of the monochromatic comodule at an odd prime, and apply the results to show non-trivialities of some products of beta and…
Characterization of the MASCOT landing area by Hayabusa2
Stefan Schröder, Naoya Sakatani, Rie Honda +26
Context. After landing on C-type asteroid Ryugu, MASCOT imaged brightly colored, submillimeter-sized inclusions in a small rock. Hayabusa2 successfully returned a sample of small p…
Rigged Hilbert Space Approach for Non-Hermite Systems with Positive Definite Metric
Shousuke Ohmori, Junichi Takahashi
We investigate Dirac's bra-ket formalism based on a rigged Hilbert space for a non-Hermite quantum system with a positive-definite metric. First, the rigged Hilbert space, characte…
Resonance-to-bound transition of He in neutron matter and its analogy with heteronuclear Feshbach molecule
Hiroyuki Tajima, Hajime Moriya, Wataru Horiuchi +2
We theoretically investigate the fate of a neutron-alpha -wave resonance in dilute neutron matter, which may be encountered in neutron stars and supernova explosions. While …
Monopoles of the Dirac type and color confinement in QCD -- First results of SU(3) numerical simulations without gauge fixing
Katsuya Ishiguro, Atsuki Hiraguchi, Tsuneo Suzuki
If non-Abelian gauge fields in QCD have a line-singularity leading to non-commutativity with respect to successive partial-derivative operations, the non-Abelian Bianchi id…
Possible condensation of Cooper triples
Sora Akagami, Hiroyuki Tajima, Kei Iida
We theoretically discuss the possible condensation of Cooper triples, which correspond to a three-body version of Cooper pairs, in three-component Fermi systems with three-body att…
Shock recovery with decaying compressive pulses: Shock effects in calcite (CaCO) around the Hugoniot elastic limit
Kosuke Kurosawa, Haruka Ono, Takafumi Niihara +12
Shock metamorphism of minerals in meteorites provides insights into the ancient Solar System. Calcite is an abundant aqueous alteration mineral in carbonaceous chondrites. Return s…
The spatial distribution of impact craters on Ryugu
Naoyuki Hirata, Tomokatsu Morota, Yuichiro Cho +40
Asteroid 162173 Ryugu has numerous craters. The initial measurement of impact craters on Ryugu, by Sugita et al. (2019), is based on Hayabusa2 ONC images obtained during the first…
Laboratory measurements of stretching band strengths of deuterated Quenched Carbonaceous Composites (D-QCC)
Tamami Mori, Takashi Onaka, Itsuki Sakon +4
The observed large variation in the abundance of deuterium (D) in the interstellar medium (ISM) suggests that a significant fraction of D may be depleted into polycyclic aromatic h…
First High-speed Video Camera Observations of a Lightning Flash Associated with a Downward Terrestrial Gamma-ray Flash
R. U. Abbasi, M. M. F. Saba, J. W. Belz +146
In this paper, we present the first high-speed video observation of a cloud-to-ground lightning flash and its associated downward-directed Terrestrial Gamma-ray Flash (TGF). The op…
A possible trial beyond the conventional random phase approximation for the su(2)-Lipkin model including the case of non-closed shell system
Y. Tsue, C. Providencia, J. da Providencia +1
Concerning the su(2)-Lipkin model, the calculation of the excitation energy to the 1st excited-state gives rise to the following fact: The two results based on the exact treatment…
Search for Spatial Correlations of Neutrinos with Ultra-High-Energy Cosmic Rays
The ANTARES collaboration, A. Albert, S. Alves +1042
For several decades, the origin of ultra-high-energy cosmic rays (UHECRs) has been an unsolved question of high-energy astrophysics. One approach for solving this puzzle is to corr…
