Dataset of gold nanoparticle sizes and morphologies extracted from literature-mined microscopy images

Kavli Affiliate: Paul Alivisatos | First 5 Authors: Akshay Subramanian, Kevin Cruse, Amalie Trewartha, Xingzhi Wang, A. Paul Alivisatos | Summary: The factors controlling the size and morphology of nanoparticles have so far been poorly understood. Data-driven techniques are an exciting avenue to explore this field through the identification of trends and correlations in data. […]

Optimizing frequency allocation for fixed-frequency superconducting quantum processors

Kavli Affiliate: Irfan Siddiqi | First 5 Authors: Alexis Morvan, Larry Chen, Jeffrey M. Larson, David I. Santiago, Irfan Siddiqi | Summary: Fixed-frequency superconducting quantum processors are one of the most mature quantum computing architectures with high-coherence qubits and low-complexity controls. However, high-fidelity multi-qubit gates pose tight requirements on individual qubit frequencies in these processors […]

GJ 367b: A dense ultra-short period sub-Earth planet transiting a nearby red dwarf star

Kavli Affiliate: George R. Ricker | First 5 Authors: Kristine W. F. Lam, Szilárd Csizmadia, Nicola Astudillo-Defru, Xavier Bonfils, Davide Gandolfi | Summary: Ultra-short-period (USP) exoplanets have orbital periods shorter than one day. Precise masses and radii of USPs could provide constraints on their unknown formation and evolution processes. We report the detection and characterization […]

Damped Ly-alpha Absorbers in Star-forming Galaxies at z < 0.15 Detected with the Hubble Space Telescope and Implications for Galaxy Evolution

Kavli Affiliate: Donald G. York | First 5 Authors: Varsha P. Kulkarni, David V. Bowen, Lorrie A. Straka, Donald G. York, Neeraj Gupta | Summary: We report {it HST} COS spectroscopy of 10 quasars with foreground star-forming galaxies at 0.02$<$$z$$<$ 0.14 within impact parameters of $sim$1-7 kpc. We detect damped/sub-damped Ly$alpha$ absorption in 100$%$ of […]

Recent advances in branching problems of representations

Kavli Affiliate: Toshiyuki Kobayashi | First 5 Authors: Toshiyuki Kobayashi, , , , | Summary: How does an irreducible representation of a group behave when restricted to a subgroup? This is part of branching problems, which are one of the fundamental problems in representation theory, and also interact naturally with other fields of mathematics. This […]
