Kavli Affiliate: Long Zhang | First 5 Authors: Guangzi Feng, Guangzi Feng, , , | Summary: We report on a high-power mid-infrared femtosecond master oscillator power amplifier (MOPA) system, employing Cr:ZnS and Cr:ZnSe polycrystals with fine-tuned doping profiles. Based on the soft-aperture Kerr-lens mode-locking in the soliton regime, the seed oscillator generates ~40-fs pulses with […]
Kavli Affiliate: Yi Zhou | First 5 Authors: Yinlong Bai, Yinlong Bai, , , | Summary: Recent advancements in 3D Gaussian Splatting (3DGS) have made a significant impact on rendering and reconstruction techniques. Current research predominantly focuses on improving rendering performance and reconstruction quality using high-performance desktop GPUs, largely overlooking applications for embedded platforms like […]
Kavli Affiliate: Zheng Zhu | First 5 Authors: Yule Ma, Yule Ma, , , | Summary: Thermalization in isolated quantum systems is governed by the eigenstate thermalization hypothesis, while strong disorder can induce its breakdown via many-body localization. Here we show that disorder can also generate a narrow band of thermal eigenstates embedded in an […]
Kavli Affiliate: Zheng Zhu | First 5 Authors: Yifan Chang, Yifan Chang, , , | Summary: Vector quantization (VQ) is a key component in discrete tokenizers for image generation, but its training is often unstable due to straight-through estimation bias, one-step-behind updates, and sparse codebook gradients, which lead to suboptimal reconstruction performance and low codebook […]
Kavli Affiliate: Long Zhang | First 5 Authors: Zehan Chen, Zehan Chen, , , | Summary: Automatically generating formal specifications from program code can greatly enhance the efficiency of program verification and enable end-to-end automation from requirements to reliable software. However, existing LLM-based approaches often struggle with programs that include complex loop structures, leading to […]
Kavli Affiliate: Gang Su | First 5 Authors: Xiang Li, Xiang Li, , , | Summary: The pursuit of high-temperature quantum anomalous Hall (QAH) insulators faces fundamental challenges, including narrow topological gaps and low Curie temperatures ($T_textC$) in existing materials. Here, we propose a transformative strategy using bilateral hydrogenation to engineer a robust QAH state […]
Kavli Affiliate: Gang Su | First 5 Authors: Han Li, Han Li, , , | Summary: The realization of quantum spin liquids (QSLs) in Kitaev magnets represents an intriguing topic in frustrated quantum magnetism. Despite prediction in the pure Kitaev honeycomb model, realization of QSLs in realistic systems and materials remain scarce. The recent discovery […]
