Search for magnetoacoustic quantum oscillations in the insulating phase of YbB $_{12}$

Ryosuke Kurihara, Atsuhiko Miyata, Koji Araki +9

A highly exotic phenomenon in solid-state physics is the observation of magnetic quantum oscillations in insulators. For instance, in the Kondo insulator YbB $_{12}$ various groups…

The Search for $K_{L} \to π^{0} π^{0} γ γ$ and $K_{L} \to π^{0} π^{0} X$ where $X \to 2 γ$ at the KOTO Experiment

J. Redeker, C. Lin, Y. W. Wah +23

We performed searches for $K_{L} \to π^{0} π^{0} X$ where $X$ may be an axion-like particle which promptly decays to two photons, and the first search for $K_{L} \to π^{0} π^{0} γ γ$ …

Identifying the Threshold Chain Length for Stress Overshoot in Ring-Linear Polymer Blends under Uniaxial Elongation: The Role of Multiple Threading

Takahiro Murashima, Katsumi Hagita, Toshihiro Kawakatsu

The rheological behavior of ring-linear polymer blends under uniaxial elongational flow has remained a subject of intense debate, particularly regarding the emergence of stress ove…

Realization of a triangular spin necklace in a verdazyl-based Ni complex

Itsuki Shimamura, Risa Yagura, Takanori Kida +6

We successfully synthesized a verdazyl-based complex, ( $m$ -Py-V) $_{3}$ [Ni(NO $_{3}$ ) $_{2}$ ], in which Ni $^{2 +}$ ions and verdazyl radicals form a one-dimensional, triangular spin necklace…

Experimental benchmark of the quantum-classical crossover in a spin ladder

Hironori Yamaguchi, Itsuki Shimamura, Akira Matsuo +4

We report a spin-(1/2, 5/2) three-leg ladder realized in a radical-Mn polymer, exhibiting an antiferromagnetic transition and magnetization curves accurately described by classical…

Search for Dark Particles in $K_{L}^{0} \to γ X$ at the KOTO Experiment

T. Wu, Y. C. Tung, Y. B. Hsiung +24

We report a search for an invisible particle $X$ in the decay $K_{L}^{0} \to γ X$ ( $X \to invisible$ ), where $X$ can be interpreted as a massless or massive dark photon. N…
