Kavli Affiliate: Kejia Lee | First 5 Authors: Shunshun Cao, Jinchen Jiang, Jaroslaw Dyks, Kejia Lee, Jiguang Lu | Summary: We analyse and model rapid rotations of polarization orientations in PSR B1919+21’s single pulses, based on FAST observation data. In more than one third of B1919+21’s single pulses, polarization angle (PA) is found to rotate […]
Kavli Affiliate: Kejia Lee | First 5 Authors: Shunshun Cao, Jinchen Jiang, Jaroslaw Dyks, Kejia Lee, Jiguang Lu | Summary: We analyze and model rapid rotations of polarization orientations in PSR B1919+21’s single pulses based on Five-hundred-meter Aperture Spherical radio Telescope observation data. In more than one-third of B1919+21’s single pulses, the polarization position angle […]
Kavli Affiliate: Luis C. Ho | First 5 Authors: Kai-Xing Lu, Yan-Rong Li, Qingwen Wu, Luis C. Ho, Zhi-Xiang Zhang | Summary: Changing-look active galactic nuclei (CL-AGNs), characterized by emerging or disappearing of broad lines accompanied with extreme continuum flux variability, have drawn much attention for their potential of revealing physical processes underlying AGN evolution. […]
Kavli Affiliate: Li Xin Li | First 5 Authors: Jingxin Liu, Xiang Gao, Yisha Li, Xin Li, Haiyang Lu | Summary: Reinforcement Learning (RL) has been widely applied in recommendation systems to capture long-term user engagement, thus improving dwelling time and improving user retention. In the context of a short video & live stream mixed […]
Kavli Affiliate: Nergis Mavalvala | First 5 Authors: Benjamin Lou, Hudson A. Loughlin, Nergis Mavalvala, , | Summary: Entanglement often increases quantum measurement schemes’ sensitivity. However, we find that in precision measurements with zero-mean Gaussian states, such as squeezed states, entanglement between different paths degrades measurement sensitivity. We prove an inverse relationship between entanglement entropy […]

Kavli Affiliate: Ke Wang | First 5 Authors: Ke Wang, Rufus Boyack, K. Levin, , | Summary: Observing the amplitude-Higgs mode in superconductors has been a central challenge in condensed matter physics. Unlike the phase mode in the electromagnetic (EM) response, the amplitude mode is not needed to satisfy gauge invariance. Indeed, it couples to […]
Kavli Affiliate: Ke Wang | First 5 Authors: Ke Wang, Rufus Boyack, K. Levin, , | Summary: Observing the “Higgs" or amplitude mode in superconductors has been a central challenge in condensed matter physics. Moreover, arriving at a theoretical understanding of this mode and how it is accessible in, say, conductivity experiments presents an additional […]
Kavli Affiliate: Claudio Ricci | First 5 Authors: Lindsay Fuller, Enrique Lopez-Rodriguez, Ismael Garcia-Bernete, Cristina Ramos Almeida, Almudena Alonso-Herrero | Summary: We present a 19.7 – 214 $mu$m imaging atlas of local (4 – 181 Mpc; median 43 Mpc) active galactic nuclei (AGN) observed with FORCAST and HAWC+ on board the SOFIA telescope with angular […]
Kavli Affiliate: Andrew Vanderburg | First 5 Authors: Madyson G. Barber, Andrew W. Mann, Andrew Vanderburg, Daniel Krolikowski, Adam Kraus | Summary: Astronomers have found more than a dozen planets transiting 10-40 million year old stars, but even younger transiting planets have remained elusive. A possible reason for the lack of such discoveries is that […]
