Gate-tunable artificial nucleus in graphene

Kavli Affiliate: Michael F. Crommie | First 5 Authors: Mykola Telychko, Keian Noori, Hillol Biswas, Dikshant Dulal, Pin Lyu | Summary: We report an atomically-precise integration of individual nitrogen (N) dopant as an in-plane artificial nucleus in a graphene device by atomic implantation to probe its gate-tunable quantum states and correlation effects. The N dopant […]

Scintillation Timescales of Bright FRBs Detected by CHIME/FRB

Kavli Affiliate: Kiyoshi Masui | First 5 Authors: Eve Schoen, Calvin Leung, Kiyoshi Masui, Daniele Michilli, Pragya Chawla | Summary: We describe a pipeline to measure scintillation in fast radio bursts (FRBs) detected by CHIME/FRB in the 400-800 MHz band by analyzing the frequency structure of the FRB’s spectrum. We use the pipeline to measure […]

Early-type galaxy density profiles from IllustrisTNG: III. Effects on outer kinematic structure

Kavli Affiliate: Risa Wechsler | First 5 Authors: Yunchong Wang, Shude Mao, Mark Vogelsberger, Volker Springel, Lars Hernquist | Summary: Early-type galaxies (ETGs) possess total radial density profiles that are largely described by singular isothermal spheres, which can lead to non-Gaussian line-of-sight velocity dispersion (LOSVD) under anisotropic stellar orbits. However, recent observations of local ETGs […]

Inferring halo masses with Graph Neural Networks

Kavli Affiliate: David N. Spergel | First 5 Authors: Pablo Villanueva-Domingo, Francisco Villaescusa-Navarro, Daniel Anglés-Alcázar, Shy Genel, Federico Marinacci | Summary: Understanding the halo-galaxy connection is fundamental in order to improve our knowledge on the nature and properties of dark matter. In this work we build a model that infers the mass of a halo […]

Large deviation principle for stochastic generalized Ginzburg-Landau equation driven by jump noise

Kavli Affiliate: Ran Wang | First 5 Authors: Ran Wang, Beibei Zhang, , , | Summary: In this paper, we establish a large deviation principle for the stochastic generalized Ginzburg-Landau equation driven by jump noise. The main difficulties come from the highly non-linear coefficient. Here we adopt a new sufficient condition for the weak convergence […]

Performance of a phonon-mediated detector using KIDs optimized for sub-GeV dark matter

Kavli Affiliate: Sunil Golwala | First 5 Authors: Osmond Wen, Taylor Aralis, Ritoban Basu Thakur, Bruce Bumble, Yen-Yung Chang | Summary: Detection of sub-GeV dark matter candidates requires sub-keV detector thresholds on deposited energy. We provide an update on a gram-scale phonon-mediated KID-based device that was designed for a dark matter search in this mass […]
