Improved Nonlocality Certification via Bouncing between Bell Operators and Inequalities

Kavli Affiliate: Ke Wang | First 5 Authors: Weikang Li, Mengyao Hu, Ke Wang, Shibo Xu, Zhide Lu | Summary: Bell nonlocality is an intrinsic feature of quantum mechanics, which can be certified via the violation of Bell inequalities. It is therefore a fundamental question to certify Bell nonlocality from experimental data. Here, we present […]

Rigidity of the subelliptic heat kernel on $operatorname{SU}(2)$

Kavli Affiliate: Jing Wang | First 5 Authors: Maria Gordina, Jing Wang, , , | Summary: We study heat kernel rigidity for the Lie group $operatorname{SU}left( 2 right)$ kernel equipped with a sub-Riemannian structure. We prove that a metric measure space equipped with a heat kernel of a special form is bundle-isometric to the Hopf […]

Little Red Dots: Rapidly Growing Black Holes Reddened by Extended Dusty Flows

Kavli Affiliate: Luis C. Ho | First 5 Authors: Zhengrong Li, Kohei Inayoshi, Kejian Chen, Kohei Ichikawa, Luis C. Ho | Summary: The James Webb Space Telescope (JWST) observations have revolutionized extragalactic research, particularly with the discovery of little red dots (LRD), which we propose are dust-reddened broad-line active galactic nuclei (AGNs). Their unique v-shape […]

The white-light superflares from cool stars in GWAC triggers

Kavli Affiliate: Jing Wang | First 5 Authors: Guang-Wei Li, Liang Wang, Hai-Long Yuan, Li-Ping Xin, Jing Wang | Summary: M-type stars are the ones that flare most frequently, but how big their maximum flare energy can reach is still unknown. We present 163 flares from 162 individual M2 through L1-type stars that triggered the […]

Spectroastrometry and Reverberation Mapping (SARM) of Active Galactic Nuclei. I. The H$β$ Broad-line Region Structure and Black Hole Mass of Five Quasars

Kavli Affiliate: Luis C. Ho | First 5 Authors: Yan-Rong Li, Chen Hu, Zhu-Heng Yao, Yong-Jie Chen, Hua-Rui Bai | Summary: We conduct a reverberation mapping (RM) campaign to spectroscopically monitor a sample of selected bright active galactic nuclei with large anticipated broad-line region (BLR) sizes adequate for spectroastrometric observations by the GRAVITY instrument on […]
