Kavli Affiliate: Jing Wang | First 5 Authors: Hong Guo, Michael G. Jones, Jing Wang, , | Summary: The growth of supermassive black holes, especially the associated state of active galactic nuclei (AGNs), is generally believed to be the key step in regulating star formation in massive galaxies. As the fuel of star formation, the […]

Kavli Affiliate: T. Higuchi | First 5 Authors: Belle II Collaboration, F. Abudinén, I. Adachi, K. Adamczyk, L. Aggarwal | Summary: We report the measurement of the branching fraction of the $B^0 to K_S^0 pi^0 gamma$ decay in $e^+ e^- to Upsilon(4S) to B overline{B}$ data recorded by the Belle II experiment at the SuperKEKB […]
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: T. Higuchi | First 5 Authors: Belle II Collaboration, F. Abudinén, I. Adachi, K. Adamczyk, L. Aggarwal | Summary: We present a reconstruction of the semileptonic decays $B^0 to pi^- e^+ nu_e$ and $B^+ to pi^0 e^+ nu_e$ in a sample corresponding to 189.3 fb$^{-1}$ of Belle II data, using events where the […]

Kavli Affiliate: Anthony Lasenby | First 5 Authors: Michael Hobson, Anthony Lasenby, , , | Summary: For conformally invariant gravity theories defined on Riemannian spacetime and having the Schwarzschild–de-Sitter (SdS) metric as a solution in the Einstein gauge, we consider whether one may conformally rescale this solution to obtain flat rotation curves, such as those […]
Kavli Affiliate: Michael Wimmer | First 5 Authors: Tom Dvir, Guanzhong Wang, Nick van Loo, Chun-Xiao Liu, Grzegorz P. Mazur | Summary: Majorana bound states constitute one of the simplest examples of emergent non-Abelian excitations in condensed matter physics. A toy model proposed by Kitaev shows that such states can arise at the ends of […]

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 […]
