Kavli Affiliate: Alexander P. Ji | First 5 Authors: Yong Yang, Geraint F. Lewis, Denis Erkal, Ting S. Li, Andrew P. Li | Summary: The Ophiuchus stellar stream presents a puzzle due to its complicated morphology, with a substructure perpendicular to the main track (spur), a broadened tail (fanning), and a shorter than expected angular […]
Kavli Affiliate: Erin Kara | First 5 Authors: Joheen Chakraborty, Erin Kara, Riccardo Arcodia, Johannes Buchner, Margherita Giustini | Summary: Quasi-periodic eruptions (QPEs) are recurring soft X-ray transients emerging from the vicinity of supermassive black holes (SMBHs) in nearby, low-mass galaxy nuclei; about ten QPE hosts have been identified thus far. Here we report the […]
Kavli Affiliate: Gordan Krnjaic | First 5 Authors: David I. Dunsky, Gordan Krnjaic, Elena Pinetti, , | Summary: Since dark matter is only known to have gravitational interactions, it may plausibly decay to gravitons on cosmological timescales. Although such a scenario can be easily realized, there are currently no known limits on this possibility based […]
Kavli Affiliate: Yi Zhou | First 5 Authors: Jin-Tao Jin, Yi Zhou, , , | Summary: We develop a comprehensive Ginzburg-Landau theory describing triple-Q magnetic orders on hexagonal lattices, focusing on $O(N)$ models with $N=2$ and $N=3$. Through systematic analysis of symmetry-allowed terms in the free energy, we establish complete phase diagrams governed by competing […]
Kavli Affiliate: Wei Gao | First 5 Authors: Kangli Wang, Wei Gao, , , | Summary: Learning-based point cloud compression methods have made significant progress in terms of performance. However, these methods still encounter challenges including high complexity, limited compression modes, and a lack of support for variable rate, which restrict the practical application of […]
Kavli Affiliate: Zheng Zhu | First 5 Authors: Guosheng Zhao, Xiaofeng Wang, Chaojun Ni, Zheng Zhu, Wenkang Qin | Summary: Combining reconstruction models with generative models has emerged as a promising paradigm for closed-loop simulation in autonomous driving. For example, ReconDreamer has demonstrated remarkable success in rendering large-scale maneuvers. However, a significant gap remains between […]
Kavli Affiliate: Yi Zhou | First 5 Authors: Hui-Ke Jin, Rong-Yang Sun, Hong-Hao Tu, Yi Zhou, | Summary: The study of strongly correlated electron systems remains a fundamental challenge in condensed matter physics, particularly in two-dimensional (2D) systems hosting various exotic phases of matter including quantum spin liquids, unconventional superconductivity, and topological orders. Although Density […]
Kavli Affiliate: Morteza Gharib | First 5 Authors: Adarsh Salagame, Shashwat Pandya, Ioannis Mandralis, Eric Sihite, Alireza Ramezani | Summary: Multi-rotors face significant risks, as actuator failures at high altitudes can easily result in a crash and the robot’s destruction. Therefore, rapid fault recovery in the event of an actuator failure is necessary for the […]
Kavli Affiliate: Wei Gao | First 5 Authors: Yuming Huang, Wei Gao, Zhiyuan Zhang, Maani Ghaffari, Dezhen Song | Summary: OpenStreetMap (OSM) has gained popularity recently in autonomous navigation due to its public accessibility, lower maintenance costs, and broader geographical coverage. However, existing methods often struggle with noisy OSM data and incomplete sensor observations, leading […]
