A photonic integrated circuit for heterogeneous second harmonic generation

Kavli Affiliate: John E. Bowers | Summary:Heterogeneous integration of GaAs-based lasers with frequency doubling waveguides presents a clear path to scalable coherent sources in the so-called green gap, yet frequency doubling systems have so far relied on separately manufactured lasers to deliver enough power for second harmonic generation. In this work, we propose a photonic […]

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) […]

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 […]
