The spontaneous breaking of CP symmetry in 4D SU() pure Yang-Mills theory at has recently attracted much attention in the context of the higher-form symmetry and the 't Ho…
Variable-Speed Teaching-Playback as Real-World Data Augmentation for Imitation Learning
Nozomu Masuya, Hiroshi Sato, Koki Yamane +3
Because imitation learning relies on human demonstrations in hard-to-simulate settings, the inclusion of force control in this method has resulted in a shortage of training data, e…
High-temperature Tl decay clarifies Pb dating in early Solar System

Radioactive nuclei with lifetimes on the order of millions of years can reveal the formation history of the Sun and active nucleosynthesis occurring at the time and place of its bi…
K-stability of pointless del Pezzo surfaces and Fano 3-folds
Hamid Abban, Ivan Cheltsov, Takashi Kishimoto +1
We explore connections between existence of -rational points for Fano varieties defined over , a subfield of , and existence of Kähler-Einstein metrics on…
Quantification of electronic asymmetry: chirality and axiality in solids
Tatsuya Miki, Hiroaki Ikeda, Michi-To Suzuki +1
Chiral and axial materials offer platforms for intriguing phenomena, such as cross-correlated responses and chirality-induced spin selectivity. However, quantifying the properties…
Transverse thermoelectric conversion in the mixed-dimensional semimetal WSi
