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…
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…
High-gain optical amplification and lasing from erbium-doped single-crystal films epitaxially grown on silicon
Xuejun Xu, Tomohiro Inaba, Takuma Aihara +3
On-chip erbium-doped optical amplifiers and lasers are essential for realizing fully integrated active silicon photonic circuits, but their performance has been limited by the low…
Bell Meets General Philosophers of Science : Reassessing Measurement Independence
Yuichiro Kitajima
Bell's inequality is derived from three assumptions: measurement independence, outcome independence, and parameter independence. Among these, measurement independence, often taken…
GW250114: testing Hawking's area law and the Kerr nature of black holes
The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1785
The gravitational-wave signal GW250114 was observed by the two LIGO detectors with a network matched-filter signal-to-noise ratio of 80. The signal was emitted by the coalescence o…
Signature of axion dark matter in low-frequency terrestrial electromagnetic fields: formulation and predictions
Atsushi Taruya, Atsushi Nishizawa, Yoshiaki Himemoto
We develop a theoretical framework for axion dark matter (DM) searches using terrestrial electromagnetic (EM) fields, enabling a global and quantitative characterization of the sig…
