Structured light, including an optical vortex with a helical wavefront, possesses unique features, such as orbital angular momentum, and it enables the twist of a myriad of materials without chirality to form exotic chiral structures.
This exotic interaction between the structured light fields and matters will provide novel fundamental sciences and advanced optical technologies to explore new horizon of materials science.

Experimental Study of Radical Reactions on Cold Ice Surfaces Using a Highly Sensitive Surface Analysis Method

Atsuki Ishibashi, Naoki Watanabe

Article type: Overview Articles
2025 Volume 80 Issue 1 Pages 11-19
Published: January 05, 2025
Released on J-STAGE: January 05, 2025

Radical reactions on the surface of interstellar dust (ice particles) are important for the formation of complex organic molecules in interstellar space. However, detection of radicals on ice surfaces in laboratory experiments is difficult with conventional methods due to sensitivity and other problems. Therefore, we developed a high-sensitivity Cs⁺ ion pickup apparatus. Using this apparatus, we succeeded in obtaining new knowledge on radical reactions on ice surfaces.

Search for the α-Condensed States in Atomic Nuclei

Satoshi Adachi, Yuki Fujikawa, Takahiro Kawabata

Article type: Researches
2025 Volume 80 Issue 1 Pages 20-25

It is theoretically suggested that α particles might condense into the same lowest 0s orbit in atomic nuclei due to their bosonic nature. This is the Bose-Einstein condensation in nucleon many-body systems. We report the recent experimental results from our exploration of the α-condensed states in ²⁰Ne and ²⁴Mg.

Excitation of Freak Waves in Magnetized Plasmas

Yusuke Kosuga, Shigeru Inagaki, Yuichi Kawachi

Article type: Researches
2025 Volume 80 Issue 1 Pages 26-30
Published: January 05, 2025

Excitation of nonlinear breathers for magnetized plasmas, in particular in the context of drift waves, is discussed. Breathers can arise as a consequence of nonlinear evolution of underlying drift waves, with self-consistent feedback from nonlinearly driven flows. Data analysis confirmed the excitation of breathers for drift waves and the transient increase of particle flux is also demonstrated.
