Electric Toroidal Quadrupoles in Spin-Orbit Coupled Metal CdReO
Satoru Hayami, Yuki Yanagi, Hiroaki Kusunose +1
We report our theoretical results on the order parameters for the pyrochlore metal CdReO, which undergoes enigmatic phase transitions with inversion symmetry breaking.…
Topological classification of the single-wall carbon nanotube
Rin Okuyama, Wataru Izumida, Mikio Eto
The single-wall carbon nanotube (SWNT) can be a one-dimensional topological insulator, which is characterized by a -topological invariant, winding number. Using the ana…
Fixed Point Quasiconvex Subgradient Method
Kazuhiro Hishinuma, Hideaki Iiduka
Constrained quasiconvex optimization problems appear in many fields, such as economics, engineering, and management science. In particular, fractional programming, which models rat…
Updated Inflight Calibration of Hayabusa2's Optical Navigation Camera (ONC) for Scientific Observations during the Cruise Phase
Eri Tatsumi, Toru Kouyama, Hidehiko Suzuki +17
The Optical Navigation Camera (ONC-T, ONC-W1, ONC-W2) onboard Hayabusa2 are also being used for scientific observations of the mission target, C-complex asteroid 162173 Ryugu. Scie…
Interplay between nuclear shell evolution and shape deformation revealed by magnetic moment of 75Cu
Y. Ichikawa, H. Nishibata, Y. Tsunoda +41
Exotic nuclei are characterized by a number of neutrons (or protons) in excess relative to stable nuclei. Their shell structure, which represents single-particle motion in a nucleu…
Dynamics of Time-Periodic Reaction-Diffusion Equations with Compact Initial Support on R
Weiwei Ding, Hiroshi Matano
This paper is concerned with the asymptotic behavior of bounded solutions of the Cauchy problem \begin{equation*} \left\{ \begin{array}{ll} u_t=u_{xx} +f(t,u), & x\in\mathbb{R},\,t…
