Structured information extraction from complex scientific text with fine-tuned large language models

Posted by dbos Berkeley

Kavli Affiliate: Kristin Persson | First 5 Authors: Alexander Dunn, John Dagdelen, Nicholas Walker, Sanghoon Lee, Andrew S. Rosen | Summary: Intelligently extracting and linking complex scientific information from unstructured text is a challenging endeavor particularly for those inexperienced with natural language processing. Here, we present a simple sequence-to-sequence approach to joint named entity recognition […]

Visualizing and manipulating chiral interface states in a moiré quantum anomalous Hall insulator

Posted by dbos Berkeley

Kavli Affiliate: Michael F. Crommie | First 5 Authors: Canxun Zhang, Tiancong Zhu, Salman Kahn, Tomohiro Soejima, Kenji Watanabe | Summary: Moir’e systems made from stacked two-dimensional materials host novel correlated and topological states that can be electrically controlled via applied gate voltages. We have used this technique to manipulate Chern domains in an interaction-driven […]

A General Framework for Removing Point Spread Function Additive Systematics in Cosmological Weak Lensing Analysis

Posted by dbos Tokyo

Kavli Affiliate: Masahiro Takada | First 5 Authors: Tianqing Zhang, Xiangchong Li, Roohi Dalal, Rachel Mandelbaum, Michael A. Strauss | Summary: Cosmological weak lensing measurements rely on a precise measurement of the shear two-point correlation function (2PCF) along with a deep understanding of systematics that affect it. In this work, we demonstrate a general framework […]

Optical Refrigeration for an Optomechanical Amplifier

Posted by dbos Caltech

Kavli Affiliate: Rana X. Adhikari | First 5 Authors: Samuel Schulz, Yehonathan Drori, Christopher Wipf, Rana X Adhikari, | Summary: We explore the viability of using optical refrigeration as a low-vibration cooling method for a phase-sensitive optomechanical amplifier proposed to improve the sensitivity of future gravitational wave detectors. We find that with moderate improvements on […]

A New Component from the Quiet Sun: Synchrotron Radiation from Galactic Cosmic-Ray Electrons

Posted by dbos Stanford

Kavli Affiliate: Vahe Petrosian | First 5 Authors: , , , , | Summary: The quiet Sun, i.e. in its non-flaring state or non-flaring regions, emits thermal radiation from radio to ultraviolet. The quiet Sun produces also non-thermal radiation observed in gamma rays due to interactions of Galactic Cosmic Rays (GCR) with the solar gas […]

Spatiotemporal control of active topological defects

Posted by dbos UCSB

Kavli Affiliate: Mark J. Bowick | First 5 Authors: Suraj Shankar, Luca V. D. Scharrer, Mark J. Bowick, M. Cristina Marchetti, | Summary: Topological defects play a central role in the physics of many materials, including magnets, superconductors and liquid crystals. In active fluids, defects become autonomous particles that spontaneously propel from internal active stresses […]
