Kavli Affiliate: Yi Zhou | First 5 Authors: Yuanyuan Qiao, Yi Zhou, , , | Summary: We investigate the global well-posedness of two-dimensional incompressible viscous and non-resistive MHD system near a non-constant equilibrium. Assuming that the initial data has certain symmetries, we can establish time-weighted lower-order energy estimates and uniform higher-order energy estimates by exploring […]
Kavli Affiliate: Yi Zhou | First 5 Authors: Yuanyuan Qiao, Yi Zhou, , , | Summary: This paper investigates the stabilization effect of a background magnetic vorticity on electrically conducting fluids. By exploring the dissipation nature of the linearized equations, we prove the global existence of smooth solutions to the two-dimensional incompressible viscous and non-resistive […]
Kavli Affiliate: Cheng Peng | First 5 Authors: Tianbao Xie, Fan Zhou, Zhoujun Cheng, Peng Shi, Luoxuan Weng | Summary: Language agents show potential in being capable of utilizing natural language for varied and intricate tasks in diverse environments, particularly when built upon large language models (LLMs). Current language agent frameworks aim to facilitate the […]
Kavli Affiliate: Gang Su | First 5 Authors: Jia-Wen Li, Gang Su, Bo Gu, , | Summary: To realize room temperature ferromagnetic (FM) semiconductors is still a challenge in spintronics. Many antiferromagnetic (AFM) insulators and semiconductors with high Neel temperature $T_N$ are obtained in experiments, such as LaFeO$_3$, BiFeO$_3$, etc. High concentrations of magnetic impurities […]
Kavli Affiliate: Long Zhang | First 5 Authors: Bei-Bei Wang, Long Zhang, , , | Summary: We investigate the dynamical characterization theory for periodically driven systems in which Floquet topology can be fully detected by emergent topological patterns of quench dynamics in momentum subspaces called band-inversion surfaces. We improve the results of a recent work […]

Kavli Affiliate: Gang Su | First 5 Authors: De-Liang Bao, Mingquan Xu, Ao-Wen Li, Gang Su, Wu Zhou | Summary: The advent of monochromated electron energy-loss spectroscopy has enabled atomic-resolution vibrational spectroscopy, which triggered interest in spatially localized or quasi-localized vibrational modes in materials. Here we report the discovery of phonon vortices at heavy impurities […]
Kavli Affiliate: Yi Zhou | First 5 Authors: Rui Yang, Li Fang, Yi Zhou, , | Summary: Text-based knowledge graph completion (KGC) methods, leveraging textual entity descriptions are at the research forefront. The efficacy of these models hinges on the quality of the textual data. This study explores whether enriched or more efficient textual descriptions […]
Kavli Affiliate: Cheng Peng | First 5 Authors: Rajan Plumley, Sougata Mardanya, Cheng Peng, Johannes Nokelainen, Tadesse Assefa | Summary: Van der Waals (vdW) magnetic materials are comprised of layers of atomically thin sheets, making them ideal platforms for studying magnetism at the two-dimensional (2D) limit. These materials are at the center of a host […]
