Search for high-pressure phases of yttrium via a data assimilation approach
Yuuki Kubo, Takahiro Ishikawa, Yuta Tanaka +3
We investigate the distorted face-centered-cubic (dfcc) phase of yttrium (Y) using a data-assimilation-based structure search that combines high-resolution powder x-ray diffraction…

Superconducting LaPtH with triatomic hydrogen units
T. Ishikawa, Y. Tanaka, S. Tsuneyuki
To veryfy "hot supreconductivity" recently proposed in lanthanum hydride-based compounds, we explored thermodynamically stable and superconducting phases in the lanthanum (La)-plat…

Assessing the possible superconductivity in doped perovskite hydride KMgH: Effects of lattice anharmonicity and spin fluctuations
Shaocong Lu, Ryosuke Akashi, Mitsuaki Kawamura +1
The superconducting properties of uniformly hole-doped perovskite hydride KMgH with varying doping concentration and lattice parameter corresponding to different pressures were…
