Kavli Affiliate: Xian Chen | First 5 Authors: Xian Chen, Zhongfu Zhang, , , | Summary: Extreme-mass-ratio inspirals (EMRIs) are important sources for space-borne gravitational-wave (GW) detectors. Such a source normally consists of a stellar-mass black hole (BH) and a Kerr supermassive BH (SMBH), but recent astrophysical models predict that the small body could also […]
Kavli Affiliate: Jing Wang | First 5 Authors: Jing Wang, Peng Yuan, Dongfang Zhang, Guoqiang Xie, Kainan Xiong | Summary: Optical quadratic nonlinearity is ultrafast in nature, while parametric interaction usually manifests only the broadband characteristic. Enormous progress has been made toward broadband phase-matching for parametric amplification and wide applications. In existing devices of broadband […]
Kavli Affiliate: Subo Dong | First 5 Authors: Jian Ge, Hui Zhang, Weicheng Zang, Hongping Deng, Shude Mao | Summary: We propose to develop a wide-field and ultra-high-precision photometric survey mission, temporarily named "Earth 2.0 (ET)". This mission is designed to measure, for the first time, the occurrence rate and the orbital distributions of Earth-sized […]
Kavli Affiliate: Jing Wang | First 5 Authors: Wenxuan Wang, Chen Chen, Jing Wang, Sen Zha, Yan Zhang | Summary: For 3D medical image (e.g. CT and MRI) segmentation, the difficulty of segmenting each slice in a clinical case varies greatly. Previous research on volumetric medical image segmentation in a slice-by-slice manner conventionally use the […]
Kavli Affiliate: Linhua Jiang | First 5 Authors: Yuming Fu, Xue-Bing Wu, Linhua Jiang, Yanxia Zhang, Zhi-Ying Huo | Summary: Quasars behind the Galactic plane (GPQs) are important astrometric references and valuable probes of the Galactic gas, yet the search of GPQs is difficult due to severe extinction and source crowding in the Galactic plane. […]
Kavli Affiliate: Feng Yuan | First 5 Authors: Hai Yang, Feng Yuan, Hui Li, Yosuke Mizuno, Fan Guo | Summary: The formation of jets in black hole accretion systems is a long-standing problem. It has been proposed that a jet can be formed by extracting the rotation energy of the black hole ("BZ-jet") or the […]

Kavli Affiliate: Ke Wang | First 5 Authors: He Liu, Ting Zhang, Ke Wang, Fei Gao, Gang Xu | Summary: Hole spins confined in semiconductor quantum dot systems have gained considerable interest for their strong spin-orbit interactions (SOIs) and relatively weak hyperfine interactions. Here we experimentally demonstrate a tunable SOI in a double quantum dot […]
Kavli Affiliate: Jing Wang | First 5 Authors: Jing Wang, Nannan Han, Zheng-Dong Luo, Mingwen Zhang, Xiaoqing Chen | Summary: Electrical tuning of second-order nonlinearity in optical materials is attractive to strengthen and expand the functionalities of nonlinear optical technologies, though its implementation remains elusive. Here, we report the electrically tunable second-order nonlinearity in atomically […]
