Kavli Affiliate: Li Xin Li | First 5 Authors: Ping Yu, Jianxiong Li, Xin Li, Gisela Schuetz, Michael Hirscher | Summary: Singular beams have attracted great attention due to their optical properties and broad applications from light manipulation to optical communications. However, there has been a lack of practical schemes with which to achieve switchable […]
Kavli Affiliate: Masahito Yamazaki | First 5 Authors: Meer Ashwinkumar, Matthew Dodelson, Abhiram Kidambi, Jacob M. Leedom, Masahito Yamazaki | Summary: We discuss ensemble averages of two-dimensional conformal field theories associated with an arbitrary indefinite lattice with integral quadratic form $Q$. We provide evidence that the holographic dual after the ensemble average is the three-dimensional […]
Kavli Affiliate: Xian Chen | First 5 Authors: Manuel Arca Sedda, Christopher P L Berry, Karan Jani, Pau Amaro-Seoane, Pierre Auclair | Summary: Since 2015 the gravitational-wave observations of LIGO and Virgo have transformed our understanding of compact-object binaries. In the years to come, ground-based gravitational-wave observatories such as LIGO, Virgo, and their successors will […]
Kavli Affiliate: Matthew Fisher | First 5 Authors: Dmitriy Smirnov, Michael Gharbi, Matthew Fisher, Vitor Guizilini, Alexei A. Efros | Summary: Artists and video game designers often construct 2D animations using libraries of sprites — textured patches of objects and characters. We propose a deep learning approach that decomposes sprite-based video animations into a disentangled […]
Kavli Affiliate: Huawei Zhang | First 5 Authors: Yang Huang, Timothy C. Beers, Christian Wolf, Young Sun Lee, Christopher A. Onken | Summary: Accurate determinations of stellar parameters and distances for large complete samples of stars are keys for conducting detailed studies of the formation and evolution of our Galaxy. Here we present stellar atmospheric […]
Kavli Affiliate: Gregory J. Herczeg | First 5 Authors: Yifan Zhou, Brendan P. Bowler, Kevin R. Wagner, Glenn Schneider, Dániel Apai | Summary: Recent discoveries of young exoplanets within their natal disks offer exciting opportunities to study ongoing planet formation. In particular, a planet’s mass accretion rate can be constrained by observing the accretion-induced excess […]
Kavli Affiliate: Troy A. Porter | First 5 Authors: Guðlaugur Jóhannesson, Troy A. Porter, , , | Summary: Cosmic-ray (CR) sources temporarily enhance the relativistic particle density in their vicinity over the background distribution accumulated from the Galaxy-wide past injection activity and propagation. If individual sources are close enough to the solar system, their localised […]

Kavli Affiliate: Vahe Petrosian | First 5 Authors: Maria Giovanna Dainotti, Vahe’ Petrosian, Luke Bowden, , | Summary: Originating from neutron star-neutron star (NS-NS) or neutron star-black hole (NS-BH) mergers, short gamma-ray bursts (SGRBs) are the first electromagnetic emitters associated with gravitational waves. This association makes the determination of SGRB formation rate (FR) a critical […]
Kavli Affiliate: L. Mahadevan | First 5 Authors: Lucy Liu, Gary P. T. Choi, L. Mahadevan, , | Summary: Kirigami, the art of introducing cuts in thin sheets to enable articulation and deployment, has become an inspiration for a novel class of mechanical metamaterials with unusual properties. Here we complement the use of periodic tiling […]
