On the string theory of a single NS5-brane

Kavli Affiliate: Emil J. Martinec | First 5 Authors: Andrea Dei, Andrea Dei, , , | Summary: We formulate a worldsheet description of string theory in the background of a single decoupled NS5-brane, which is a particularly simple example of “little string” holography. The worldsheet theory involves a gauged Wess-Zumino-Witten model for the group coset […]

Increasing single-photon production with cavity-QED

Kavli Affiliate: John E. Bowers | Summary:A study was performed to determine the extent cavity enhancement may increase single-photon production while maintaining single-photon purity. It was found that certain combinations of cavity lifetime and light-matter coupling strength can lead to carrier-photon correlations that increase single-photon generation rate while maintaining low 2nd order photon correlation. This […]

TDCOSMO XXIV. First spatially resolved kinematics of the lens galaxy obtained using JWST-NIRSpec to improve time-delay cosmography

Kavli Affiliate: Joshua Frieman | Summary:Spatially resolved stellar kinematics has become a key ingredient in time-delay cosmography to break the mass-sheet degeneracy in the mass profile and in turn provide a precise constraint on the Hubble constant and other cosmological parameters. In this paper, we present the first measurements of 2D resolved stellar kinematics for […]

Mapping the projectional architecture of the mouse midbrain dopaminergic system using cell type-specific barcoding

Kavli Affiliate: Justus M Kebschull | Authors: Hyopil Kim, Cheng Xu, Craig Washington, Maggie Lowmann and Justus M Kebschull | Summary: Brain-wide neural circuits are formed by the diverse axonal branching patterns of many individual neurons. Here we introduce POINTseq (projections of interest by sequencing), a high-throughput and user-friendly barcoded connectomics method that uses cell […]

Sifting for a Stream: The Morphology of the $300S$ Stellar Stream

Kavli Affiliate: Alexander Ji | Summary:Stellar streams are sensitive laboratories for understanding the small-scale structure in our Galaxy’s gravitational field. Here, we analyze the morphology of the $300S$ stellar stream, which has an eccentric, retrograde orbit and thus could be an especially powerful probe of both baryonic and dark substructures within the Milky Way. Due […]

High-quality metalens enables minimally invasive CFB endoscopy

Kavli Affiliate: Feng Wang | First 5 Authors: Ruixiang Song, Ruixiang Song, , , | Summary: Metalenses, owing to their ultra-thin planar structures, present a promising solution for reducing endoscopic invasiveness. However, achieving high-quality imaging with minimal invasiveness (short focal length of metalens) remains a critical challenge. This paper presents a deep learning assisted metalens […]
