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 […]

Postselection in lattice bosons undergoing continuous measurements

Kavli Affiliate: Matthew P. A. Fisher | First 5 Authors: Diego Barberena, Matthew P. A. Fisher, , , | Summary: We study in detail the postselection problem in a specific model: bosons hopping on a lattice subjected to continuous local measurements of quadrature observables. We solve the model analytically and show that the postselection overhead […]

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 […]
