Kavli Affiliate: Jeffrey B. Neaton | First 5 Authors: Norm M. Tubman, Christopher J. N. Coveney, Chih-En Hsu, Andres Montoya-Castillo, Marina R. Filip | Summary: Ab initio downfolding describes the electronic structure of materials within a low-energy subspace, often around the Fermi level. Typically starting from mean-field calculations, this framework allows for the calculation of […]
Kavli Affiliate: Gabor Furesz | Summary:The Teledyne COSMOS-66 is a next-generation CMOS camera designed for astronomical imaging, featuring a large-format sensor ($8120 times 8120$ pixels, each $10 μm$), high quantum efficiency, high frame rates, and a correlated multi-sampling mode that achieves low read noise. We performed a suite of bench-top and on-sky tests to characterize […]
Kavli Affiliate: Michael McDonald | Summary:We discuss our transient search for directed energy systems in local galaxies, with calculations indicating the ability of modest searches to detect optical Search for Extraterrestrial Intelligence (SETI) sources in the closest galaxies. Our analysis follows Lubin (2016) where a messenger civilization follows a beacon strategy we call "intelligent targeting." […]

Kavli Affiliate: Ke Wang | First 5 Authors: Lehao Lin, Ke Wang, Maha Abdallah, Wei Cai, | Summary: In recent years, the rapid development of artificial intelligence (AI) especially multi-modal Large Language Models (MLLMs), has enabled it to understand text, images, videos, and other multimedia data, allowing AI systems to execute various tasks based on […]
Kavli Affiliate: Feng Wang | First 5 Authors: Feng Wang, Zhongguo Sun, Xiangyu Hu, , | Summary: This paper presents a Weakly Compressible Smoothed Particle Hydrodynamics (WCSPH) method for solving the two-equation Reynolds-Averaged Navier-Stokes (RANS) model. The turbulent wall-bounded flow with or without mild flow separation, a crucial flow pattern in engineering applications, yet rarely […]
Kavli Affiliate: Mazhar Ali | Summary: Higher-order topological insulators (HOTIs) represent a novel class of topological materials, characterised by the emergence of topological boundary modes at dimensions two or more lower than those of bulk materials. Recent experimental studies have identified conducting channels at the hinges of HOTIs, although their topological nature remains unexplored. In […]
Kavli Affiliate: Michael Crommie | Summary:Excitonic insulators represent a unique quantum phase of matter, providing a rich ground for studying exotic quantum bosonic states. Strongly coupled electron-hole bilayers, which host stable dipolar exciton fluids with an exciton density that can be adjusted electrostatically, offer an ideal platform to investigate correlated excitonic insulators. Based on electron-hole […]

Kavli Affiliate: Daniel E. Holz | First 5 Authors: Kristen Schumacher, Colm Talbot, Daniel E. Holz, Nicolás Yunes, | Summary: In some beyond-Einstein theories of gravity, gravitational waves can contain up to six polarizations, which are allowed to propagate at different speeds faster than light. These different propagation speeds imply that polarizations generated by the […]
