We present numerical simulation of the X-ray magnetic circular dichroism (XMCD) of the and edges of Ru in antiferromagnetic RuO using a combination of densi…
An extremely energetic cosmic ray observed by a surface detector array
Telescope Array Collaboration
Cosmic rays are energetic charged particles from extraterrestrial sources, with the highest energy events thought to come from extragalactic sources. Their arrival is infrequent, s…
Spin current relaxation time in thermally evaporated naphthyl diamine derivative films
Eiji Shikoh, Yuichiro Onishi, Yoshio Teki
The spin relaxation time (tau) on the spin transport in thermally evaporated thin films of a naphthyl diamine derivative: N, N'-Bis(naphthalen-1-yl)-N, N'-bis(phenyl)-2,2'-dimethyl…
Balanced metrics for extremal Kähler metrics and Fano manifolds
Yoshinori Hashimoto
The first three sections of this paper are a survey of the author's work on balanced metrics and stability notions in algebraic geometry. The last section is devoted to proving the…
Direct Measurement of the Spectral Structure of Cosmic-Ray Electrons+Positrons in the TeV Region with CALET on the International Space Station
O. Adriani, Y. Akaike, K. Asano +77
Detailed measurements of the spectral structure of cosmic-ray electrons and positrons from 10.6 GeV to 7.5 TeV are presented from over 7 years of observations with the CALorimetric…
Constraints on metastable superheavy dark matter coupled to sterile neutrinos with the Pierre Auger Observatory
The Pierre Auger Collaboration, A. Abdul Halim, P. Abreu +368
Dark matter particles could be superheavy, provided their lifetime is much longer than the age of the universe. Using the sensitivity of the Pierre Auger Observatory to ultra-high…
Enhanced classical radiation damping of electronic cyclotron motion in the vicinity of the Van Hove singularity in a waveguide
Yuki Goto, Savannah Garmon, Tomio Petrosky
We study the damping process of electron cyclotron motion and the resulting emission in a waveguide using the classical Friedrichs model without relying on perturbation analysis su…
Machine learning analysis of dimensional reduction conjecture for nonequilibrium Berezinskii-Kosterlitz-Thouless transition in three dimensions
Taiki Haga
We investigate the recently proposed dimensional reduction conjecture in driven disordered systems using a machine learning technique. The conjecture states that a static snapshot…
Intersections of ultracold atomic polarons and nuclear clusters: How is a chart of nuclides modified in dilute neutron matter?
Hiroyuki Tajima, Hajime Moriya, Wataru Horiuchi +2
Neutron star observations, as well as experiments on neutron-rich nuclei, used to motivate one to look at degenerate nuclear matter from its extreme, namely, pure neutron matter. A…
4 electron temperature driven ultrafast electron localization
Kohei Yamagami, Hiroki Ueda, Urs Staub +9
Valence transitions in strongly correlated electron systems are caused by orbital hybridization and Coulomb interactions between localized and delocalized electrons. The transition…
