Michell-Prager type truss structures constructed from integrable discrete power function and discrete logarithmic function
Motoki Masada, Kentaro Hayakawa, Kazuki Hayashi +3
The Michell-Prager type truss structures are constructed from the integrable discrete power and logarithmic functions. It is demonstrated that specific sublattices, subject to suit…
Development of a cosmic ray detector using CMOS sensors embedded in smartphones and Raspberry Pi devices
Wakiko Takano, Shigeharu Udo, Atsushi Shiomi +1
Cosmic rays are ubiquitous; however, their direct observation traditionally demands specialized, high-cost hardware and significant technical expertise, presenting a high barrier f…
COSMOS: A numerical relativity code specialized for PBH formation
Chul-Moon Yoo, Hirotada Okawa, Albert Escrivà +7
Primordial black holes (PBHs) are black holes generated in the early universe without having gone through stellar evolution. In the standard formation process, PBHs are formed from…
Magnetoelastic effects in the metallic frustrated antiferromagnet CrB
Tadataka Watanabe, Mai Watanabe, Sakurako Suganuma +2
Hexagonal chromium diboride CrB is a metallic frustrated antiferromagnet with a Néel temperature 88 K. In CrB, Cr 3 electrons not only give rise to localized…
Pressure Effects on CeMnSi: Evolution of Ce 4f and Mn 3d Electronic States and Negative Thermal Expansion
Sae Nishiyama, Haruka Mima, Jun-ichi Hayashi +6
We investigated pressure effects on the nontrivial heavy-fermion antiferromagnet CeMnSi by means of electrical resistivity and powder X-ray diffraction. With increasing pressure, t…
Freestanding GdBa2Cu3O7 Thin Films via Optimized Buffer Layer Design: Preserving Superconducting Properties
Kazumasa Iida, Kai Walter, Takafumi Hatano +5
Freestanding GdBa2Cu3O7 (GdBCO) superconducting thin films were fabricated using a water-soluble Sr3Al2O6 (SAO) sacrificial layer in combination with thermal release tape. An amorp…
