EvTTC: An Event Camera Dataset for Time-to-Collision Estimation

Kavli Affiliate: Yi Zhou | First 5 Authors: Kaizhen Sun, Jinghang Li, Kuan Dai, Bangyan Liao, Wei Xiong | Summary: Time-to-Collision (TTC) estimation lies in the core of the forward collision warning (FCW) functionality, which is key to all Automatic Emergency Braking (AEB) systems. Although the success of solutions using frame-based cameras (e.g., Mobileye’s solutions) […]

Successive magnetic transitions in the spin-5/2 easy-axis triangular-lattice antiferromagnet Na$_2$BaMn(PO$_4$)$_2$: A neutron diffraction study

Kavli Affiliate: Gang Su | First 5 Authors: Chuandi Zhang, Junsen Xiang, Cheng Su, Denis Sheptyakov, Xinyang Liu | Summary: Motivated by the recent observations of various exotic quantum states in the equilateral triangular-lattice phosphates Na$_2$BaCo(PO$_4$)$_2$ with $Jrm_{eff}$ = 1/2 and Na$_2$BaNi(PO$_4$)$_2$ with $S$ = 1, the magnetic properties of spin-5/2 antiferromagnet Na$_2$BaMn(PO$_4$)$_2$, their classical […]

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 […]

Preparation and observation of anomalous counterpropagating edge states in a periodically driven optical Raman lattice

Kavli Affiliate: Long Zhang | First 5 Authors: Hongting Hou, Long Zhang, , , | Summary: Motivated by the recent observation of real-space edge modes with ultracold atoms [Braun et al., Nat. Phys. 20, 1306 (2024)], we investigate the preparation and detection of anomalous counterpropagating edge states — a defining feature of the anomalous Floquet […]

D-commuting SYK model: building quantum chaos from integrable blocks

Kavli Affiliate: Cheng Peng | First 5 Authors: Ping Gao, Han Lin, Cheng Peng, , | Summary: We construct a new family of quantum chaotic models by combining multiple copies of integrable commuting SYK models. As each copy of the commuting SYK model does not commute with others, this construction breaks the integrability of each […]

Sobolev Versus Homogeneous Sobolev Extension

Kavli Affiliate: Zheng Zhu | First 5 Authors: Pekka Koskela, Riddhi Mishra, Zheng Zhu, , | Summary: In this paper, we study the relationship between Sobolev extension domains and homogeneous Sobolev extension domains. Precisely, we obtain the following results. 1- Let $1leq qleq pleq infty$. Then a bounded $(L^{1, p}, L^{1, q})$-extension domain is also […]
