Spatial deformation of many-body quantum chaotic systems and quantum information scrambling

Kavli Affiliate: Masahiro Nozaki | First 5 Authors: Kanato Goto, Taozhi Guo, Tomoki Nosaka, Masahiro Nozaki, Shinsei Ryu | Summary: We study the effect of spatial inhomogeneity on quantum information scrambling, a process of spreading and locally hiding quantum information in quantum many-body systems. As a paradigmatic example, we consider the quantum chaotic Ising spin […]

Aspects of higher-point functions in BCFT$_d$

Kavli Affiliate: Xinan Zhou | First 5 Authors: Junding Chen, Xinan Zhou, , , | Summary: We study three-point correlation functions of scalar operators in conformal field theories with boundaries and interfaces. We focus on two cases where there are one bulk and two boundary operators (B$partialpartial$), or two bulk and one boundary operators (BB$partial$). […]

Two-stream instability with a growth rate insensitive to collisions in a dissipative plasma jet

Kavli Affiliate: Yi Zhou | First 5 Authors: Yi Zhou, Paul M. Bellan | Summary: The two-stream instability (Buneman instability) is traditionally derived as a collisionless instability with the presumption that collisions inhibit this instability. We show here via a combination of a collisional two-fluid model and associated experimental observations made in the Caltech plasma […]

Edge-cloud Collaborative Learning with Federated and Centralized Features

Kavli Affiliate: Yi Zhou | First 5 Authors: Zexi Li, Qunwei Li, Yi Zhou, Wenliang Zhong, Guannan Zhang | Summary: Federated learning (FL) is a popular way of edge computing that doesn’t compromise users’ privacy. Current FL paradigms assume that data only resides on the edge, while cloud servers only perform model averaging. However, in […]

OccFormer: Dual-path Transformer for Vision-based 3D Semantic Occupancy Prediction

Kavli Affiliate: Zheng Zhu | First 5 Authors: Yunpeng Zhang, Zheng Zhu, Dalong Du | Summary: The vision-based perception for autonomous driving has undergone a transformation from the bird-eye-view (BEV) representations to the 3D semantic occupancy. Compared with the BEV planes, the 3D semantic occupancy further provides structural information along the vertical direction. This paper […]

Uncertainty-inspired Open Set Learning for Retinal Anomaly Identification

Kavli Affiliate: Yi Zhou | First 5 Authors: Meng Wang, Tian Lin, Lianyu Wang, Aidi Lin, Ke Zou | Summary: Failure to recognize samples from the classes unseen during training is a major limitation of artificial intelligence in the real-world implementation for recognition and classification of retinal anomalies. We established an uncertainty-inspired open-set (UIOS) model, […]

Acceleration-Based Kalman Tracking for Super-Resolution Ultrasound Imaging in vivo

Kavli Affiliate: Biao Huang | Authors: Biao Huang, Jipeng Yan, Megan Morris, Victoria Sinnett, Navita Somaiah, Meng-Xing Tang | Summary: Super-resolution ultrasound can image microvascular structure and flow at sub-wave-diffraction resolution based on localising and tracking microbubbles. Currently, tracking microbubbles accurately under limited imaging frame rates and high microbubble concentrations remains a challenge, especially under […]
