How Good Are Frontier Models at Physics? Expert Re-Grading Reveals Broken Evaluations and Near-Saturation of Leading Benchmarks
Ali Ansari, Haoran Sun, Andy Zeyi Liu +48
Low reported scores on leading physics benchmarks, including those featured in the Artificial Analysis Intelligence Index (2026), suggest that frontier language models still strugg…
High-Temperature ferromagnetism from site-selective filling in (Fe,Ni)GeTe
Tyler L. Werner, Jonathan T. Reichanadter, Xiang Chen +23
The discovery of high-temperature ferromagnetism in the metallic van der Waals (vdW) system FeGeTe has brought two-dimensional (2D) magnets into technologically relevant te…
Self-Assembled H2NC Molecular Lattices as a Platform for Tunable Quantum Superlattices
Adrian Bahri, Zhibo Kang, Ziyan Zhu +3
Compared to van der Waals moiré systems, molecular assembly has emerged as an exciting alternative platform for superlattice engineering via heterointegration. The electronic prope…
Photoinduced metastable cation disorder in metal halide double perovskites
Shunran Li, Burak Guzelturk, Conrad A. Kocoj +18
Lead-free perovskites have emerged as environmentally benign alternatives to lead-halide counterparts for optoelectronics. Among them, the double perovskite Cs2AgInCl6 family exhib…
Superconductivity suppression and bilayer decoupling in Pr substituted YBaCuO
Jinming Yang, Zheting Jin, Siqi Wang +17
The mechanism behind superconductivity suppression induced by Pr substitutions in YBaCuO (YBCO) has been a mystery since its discovery: in spite of being isovalent…
Sub-tesla on-chip nanomagnetic metamaterial platform for angle-resolved photoemission spectroscopy
Wenxin Li, Wisha Wanichwecharungruang, Mingyang Guo +14
Magnetically controlled states in quantum materials are central to their unique electronic and magnetic properties. However, direct momentum-resolved visualization of these states…
