OpenMX, a first-principles electronic structure calculation software, is a computational code based on density functional theory primarily used to determine the stable structure and electronic states of materials. This study attempted to develop a method for accelerating calculations using OpenMX by employing a GPU, Graphics Processing Unit, typically used for image processing. Test calculations on a 512-atom diamond structure silicon system achieved approximately double the speed compared to CPU-based calculations. Furthermore, for noncollinear calculations used in magnetic structure calculations, a 384-atom silicon system achieved 2.6 times faster speed than the CPU. Especially, GPU acceleration for noncollinear calculations is unprecedented. The results obtained in this study enable the handling of larger systems than previously possible in first-principles electronic structure calculations.

Metallization and pressure-induced superconductivity in carrier doped excitonic insulator (Ta$$_{1-x}$$Ti$$_x$$)$$_2$$NiSe$$_5$$

Tsuchida, Shun*; Hirose, Yusuke; Sekikawa, Takuya; Ono, Yoshiaki*; Hirahara, Takuya*; Sano, Sumika*; Kawaguchi, Shogo*; Kobayashi, Shintaro*; Uwatoko, Yoshiya*; Settai, Rikio*

We investigated the carrier doping effect on an excitonic insulator Ta$$_2$$NiSe$$_5$$ by means of the electrical resistivity $$rho$$ and Hall coefficient $$R_{rm H}$$ using single crystals of (Ta$$_{1-x}$$Ti$$_x$$)$$_2$$NiSe$$_5$$, and band calculation. The excitonic transition temperature $$T_{rm c}$$ is continuously suppressed to 83 K at $$x$$ = 0.104 while preserving the crystal structure. With increasing substitution concentration $$x$$, a semiconducting increment of $$rho$$ and $$R_{rm H}$$ is strongly suppressed and a metallic behavior is observed at $$x$$ > 0.06. Ti substitution can realize an excitonic correlated metallic state. This metallization is explained by the hole doping effect based on the band calculations. Applying pressure to the carrier doped (Ta$$_{1-x}$$Ti$$_x$$)$$_2$$NiSe$$_5$$, we found superconductivity above 2.6 GPa, which is much smaller than that of Ta$$_2$$NiSe$$_5$$ around 8 GPa. The carrier doping induced by Ti substitution favors superconductivity in this compound.

Hidden order state under uni-axial stress in URu$$_2$$Si$$_2$$

Kambe, Shinsaku; Ishitobi, Takayuki; Harima, Hisatomo*

Journal of the Physical Society of Japan, 94(10), p.104703_1 - 104703_5, 2025/10

https://doi.org/10.7566/JPSJ.94.104703

Hidden order state in URu$$_2$$Si$$_2$$ under uni-axial stress along [100] and [110] directions is investigated. Induced space groups and order parameters under uni-axial stress are deduced based on experimental facts and group-theoretical considerations. A scheme to identify the order parameter of hidden ordering using measurements under uni-axial stress is proposed.

An experiment to search for Og isotopes using the $$^{50}$$Ti beam impinging on $$^{248}$$Cm target was performed at RIKEN Nishina Center. The optimal beam energy was determined from the quasielastic barrier distribution extracted from the excitation function of quasielastic backscattering. As a result, no Og decay was found, enabling only an estimation of the sensitivity for one event of 0.27 pb, and the 1$$sigma$$ cross section upper limit of 0.50 pb.
