Kavli Affiliate: Emil J. Martinec | First 5 Authors: Emil J. Martinec, , , , | Summary: This companion paper to arXiv:2109.00065 explores the interpretation of $AdS_3/CFT_2$ duality for $k=(R_{AdS}/lstr)^2<1$ in terms of "non-critical little string theory". We review the underlying fivebrane structure of 1/2-BPS backgrounds for string theory in both the critical dimension and […]
Kavli Affiliate: Stephan S. Meyer | First 5 Authors: Craig Hogan, Stephan S. Meyer, , , | Summary: We consider the hypothesis that nonlocal, omnidirectional, causally-coherent quantum entanglement of inflationary horizons may account for some well-known measured anomalies of Cosmic Microwave Background (CMB) anisotropy on large angular scales. It is shown that causal coherence can […]
Kavli Affiliate: Gregory J. Herczeg | First 5 Authors: Saumya Gupta, Jessy Jose, Surhud More, Swagat R. Das, Gregory J. Herczeg | Summary: Low mass star formation inside massive clusters is crucial to understand the effect of cluster environment on processes like circumstellar disk evolution, planet and brown dwarf formation. The young massive association of […]
Kavli Affiliate: David N. Spergel | First 5 Authors: Francisco Villaescusa-Navarro, Shy Genel, Daniel Angles-Alcazar, Leander Thiele, Romeel Dave | Summary: We present the Cosmology and Astrophysics with MachinE Learning Simulations (CAMELS) Multifield Dataset, CMD, a collection of hundreds of thousands of 2D maps and 3D grids containing many different properties of cosmic gas, dark […]
Kavli Affiliate: Joel E. Moore | First 5 Authors: Maxime Dupont, Joel E. Moore, , , | Summary: Quantum criticality emerges from the collective behavior of many interacting quantum particles, often at the transition between different phases of matter. It is one of the cornerstones of condensed matter physics, which we access on noisy intermediate-scale […]
Kavli Affiliate: Daphna Shohamy | Authors: David L Barack, Akram Bakkour, Daphna Shohamy and C Daniel Salzman | Summary: Abstract In the real world, making sequences of decisions to achieve goals often depends upon the ability to learn aspects of the environment that are not directly perceptible. Learning these so-called latent features requires seeking information […]
Kavli Affiliate: Grace Xing | First 5 Authors: Len van Deurzen, Ryan Page, Vladimir Protasenko, Huili, Xing | Summary: We demonstrate the first optically pumped sub-300 nm UV laser structures grown by plasma-assisted molecular beam epitaxy on single-crystal bulk AlN. The edge-emitting laser structures fabricated with the AlN/AlGaN heterostructures exhibit multi-mode emission with peak gain […]
Kavli Affiliate: Tom Melia | First 5 Authors: John A. Tomsick, Steven E. Boggs, Andreas Zoglauer, Eric Wulf, Lee Mitchell | Summary: The Compton Spectrometer and Imager (COSI) is a 0.2-5 MeV Compton telescope capable of imaging, spectroscopy, and polarimetry of astrophysical sources. Such capabilities are made possible by COSI’s germanium cross-strip detectors, which provide […]
Kavli Affiliate: Xiang Zhang | First 5 Authors: Yihang Yin, Qingzhong Wang, Siyu Huang, Haoyi Xiong, Xiang Zhang | Summary: Contrastive learning has been widely applied to graph representation learning, where the view generators play a vital role in generating effective contrastive samples. Most of the existing contrastive learning methods employ pre-defined view generation methods, […]
Kavli Affiliate: Rainer Weiss | Summary:This Horizon Study describes a next-generation ground-based gravitational-wave observatory: Cosmic Explorer. With ten times the sensitivity of Advanced LIGO, Cosmic Explorer will push gravitational-wave astronomy towards the edge of the observable universe ($z sim 100$). The goals of this Horizon Study are to describe and evaluate design concepts for Cosmic […]
