Expansion of momentum space and full 2 π solid angle photoelectron collection in laser-based angle-resolved photoemission spectroscopy by applying sample bias

Taimin Miao, Yu Xu, 梁波, Wenpei Zhu et autres

Angle-resolved photoemission spectroscopy (ARPES) directly probes the energy and momentum of electrons in quantum materials, but conventional setups capture only a small fraction of the full 2π solid angle. This limitation is acute in laser-based ARPES, where the low photon energy restricts …

Vidar: Embodied Video Diffusion Model for Generalist Manipulation

Feng Yao, Chendong Xiang, Guodong Liu, Hang Su et autres

Scaling general-purpose manipulation to new robot embodiments remains challenging: each platform typically needs large, homogeneous demonstrations, and end-to-end pixel-to-action pipelines may degenerate under background and viewpoint shifts. Based on previous advances in video-based robot control, we present Vidar, consisting of an embodied …

Catalytic Mechanism Studies of Ortho–para H 2 Conversion Over Iron Oxide Catalysts

Yusen Chen, Hongying Zhuo, Zheng Shen, Nan Yin et autres

ABSTRACT Hydrogen serves as an ideal clean energy with zero carbon emissions, whereas its large‐scale application relies on its liquidation, by which the catalytic conversion of ortho–para H 2 at cryogenic temperature is inevitable with iron oxides as a promising catalyst. In …

Van Hove singularity driven emergence of multiple flat band-like nondispersive features in kagome superconductors

Hailan Luo, Lin Zhao, Zhen Wei Zhao, Haitao Yang et autres

The newly discovered kagome superconductors $A{\mathrm{V}}_{3}{\mathrm{Sb}}_{5}$ ($A$ = K, Rb, and Cs) continue to bring surprises in generating unusual phenomena and physical properties, including the anomalous Hall effect, unconventional charge density wave, electronic nematicity, and time-reversal symmetry breaking. Here we report an …
