Kavli Affiliate: Rainer Weiss | First 5 Authors: D. H. Shoemaker, Stefan Ballmer, Matteo Barsuglia, E. Berger, Emanuele Berti | Summary: The workshop Dawn VI: Next Generation Observatories took place online over three days, 5-7 October, 2021. More than 200 physicists and astronomers attended to contribute to, and learn from, a discussion of next-generation ground-based […]
Kavli Affiliate: Misao Sasaki | First 5 Authors: Shi Pi, Misao Sasaki, , , | Summary: In the curvaton scenario, the curvature perturbation is generated after inflation at the curvaton decay, which may have a prominent non-Gaussian effect. For a model with a non-trivial kinetic term, an enhanced curvature perturbation on a small scale can […]

Kavli Affiliate: Misao Sasaki | First 5 Authors: Chul-Moon Yoo, Tomohiro Harada, Shin’ichi Hirano, Hirotada Okawa, Misao Sasaki | Summary: We numerically study the primordial black hole (PBH) formation by an isocurvature perturbation of a massless scalar field on super Hubble scales in the radiation-dominated universe. As a first step we perform simulations of spherically […]
Kavli Affiliate: Jing Wang | First 5 Authors: Shaofu Xu, Jing Wang, Sicheng Yi, Weiwen Zou, | Summary: Tensor analytics lays mathematical basis for the prosperous promotion of multiway signal processing. To increase computing throughput, mainstream processors transform tensor convolutions to matrix multiplications to enhance parallelism of computing. However, such order-reducing transformation produces data duplicates […]
Kavli Affiliate: Austin Joyce | First 5 Authors: James Bonifacio, Kurt Hinterbichler, Austin Joyce, Diederik Roest, | Summary: The special galileon and Dirac-Born-Infeld (DBI) theories are effective field theories of a single scalar field that have many interesting properties in flat space. These theories can be extended to all maximally symmetric spaces, where their algebras […]
Kavli Affiliate: Eiichiro Komatsu | First 5 Authors: Laura Herold, Elisa G. M. Ferreira, Eiichiro Komatsu, , | Summary: A dark energy-like component in the early universe, known as early dark energy (EDE), is a proposed solution to the Hubble tension. Currently, there is no consensus in the literature as to whether EDE can simultaneously […]
Kavli Affiliate: Ke Wang | First 5 Authors: Run Xiao, Jacob T Held, Jeffrey Rable, Supriya Ghosh, Ke Wang | Summary: Magnetic doping of topological quantum materials provides an attractive route for studying the effects of time-reversal symmetry breaking. Thus motivated, we explore the introduction of the transition metal Mn into thin films of the […]
Kavli Affiliate: Peter W. Graham | First 5 Authors: Michael A. Fedderke, Peter W. Graham, Surjeet Rajendran, , | Summary: A major challenge for gravitational-wave (GW) detection in the $mu$Hz band is engineering a test mass (TM) with sufficiently low acceleration noise. We propose a GW detection concept using asteroids located in the inner Solar […]
