Universal approach to light driven “superconductivity” via preformed pairs

Kavli Affiliate: Ke Wang | First 5 Authors: , , , , | Summary: While there are many different mechanisms which have been proposed to understand the physics behind light induced “superconductivity", what seems to be common to the class of materials in which this is observed are strong pairing correlations, which are present in […]

Towards Flexible 3D Perception: Object-Centric Occupancy Completion Augments 3D Object Detection

Kavli Affiliate: Feng Wang | First 5 Authors: Chaoda Zheng, Feng Wang, Naiyan Wang, Shuguang Cui, Zhen Li | Summary: While 3D object bounding box (bbox) representation has been widely used in autonomous driving perception, it lacks the ability to capture the precise details of an object’s intrinsic geometry. Recently, occupancy has emerged as a […]

Analysis of long-lived effects in high-repetition-rate stroboscopic transient X-ray absorption experiments on thin films

Kavli Affiliate: Robert Rosner| First 5 Authors: Tobias Lojewski, Tobias Lojewski, , , | Summary:Time-resolved X-ray absorption spectroscopy (tr-XAS) has been shown to be a versatile measurement technique for investigating non-equilibrium dynamics. Novel X-ray free electron laser (XFEL) facilities like the European XFEL offer increased repetition rates for stroboscopic XAS experiments through a burst operation […]

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) […]

Origin of Increased Curie Temperature in Lithium-Substituted Ferroelectric Niobate Perovskite: Enhancement of the Soft Polar Mode

Kavli Affiliate: Ke Wang | First 5 Authors: Hao-Cheng Thong, Fang-Zhou Yao, Xian-Xian Cai, Ze Xu, Mao-Hua Zhang | Summary: The functionality of ferroelectrics is often constrained by their Curie temperature, above which depolarization occurs. Lithium (Li) is the only experimentally known substitute that can increase the Curie temperature in ferroelectric niobate-based perovskites, yet the […]
