Fractionalized Kohn-Sham ansatz for strongly-correlated electrons

Kavli Affiliate: Zheng Zhu | First 5 Authors: Bo Zhao, Jingyu Zhao, Zheng Zhu, Jian Wu, Zheng Liu | Summary: We propose to expand the territory of density functional theory to strongly-correlated electrons by reformulating the Kohn-Sham ansatz in the representation of fractionalized particles. We call it the ”KS* ansatz”. Using inhomogeneous t-J chains as […]

ReconDreamer: Crafting World Models for Driving Scene Reconstruction via Online Restoration

Kavli Affiliate: Zheng Zhu | First 5 Authors: Chaojun Ni, Guosheng Zhao, Xiaofeng Wang, Zheng Zhu, Wenkang Qin | Summary: Closed-loop simulation is crucial for end-to-end autonomous driving. Existing sensor simulation methods (e.g., NeRF and 3DGS) reconstruct driving scenes based on conditions that closely mirror training data distributions. However, these methods struggle with rendering novel […]

Rigidity Results for Compact Submanifolds with Pinched Ricci Curvature in Euclidean and Spherical Space Forms

Kavli Affiliate: Yi Zhou | First 5 Authors: Jianquan Ge, Ya Tao, Yi Zhou, , | Summary: For compact submanifolds in Euclidean and Spherical space forms with Ricci curvature bounded below by a function $alpha(n,k,H,c)$ of mean curvature, we prove that the submanifold is either isometric to the Einstein Clifford torus, or a topological sphere […]
