The {it AGORA} High-resolution Galaxy Simulations Comparison Project. VIII: Disk Formation and Evolution of Simulated Milky Way Mass Galaxy Progenitors at $1<z<5$

Posted by dbos Stanford

Kavli Affiliate: Tom Abel | First 5 Authors: Minyong Jung, Ji-hoon Kim, Thinh H. Nguyen, Ramon Rodriguez-Cardoso, Santi Roca-Fàbrega | Summary: We investigate how differences in the stellar feedback produce disks with different morphologies in Milky Way-like progenitors over 1 $leq z leq 5$, using eight state-of-the-art cosmological hydrodynamics simulation codes in the textit{AGORA} project. […]

A Hubbard exciton fluid in a photo-doped antiferromagnetic Mott insulator

Posted by klaurent Caltech

Kavli Affiliate: David Hsieh| Summary:The undoped antiferromagnetic Mott insulator naturally has one charge carrier per lattice site. When it is doped with additional carriers, they are unstable to spin fluctuation-mediated Cooper pairing as well as other unconventional types of charge, spin, and orbital current ordering. Photo-excitation can produce charge carriers in the form of empty […]

Observation of excitons bound by antiferromagnetic correlations

Posted by klaurent Caltech

Kavli Affiliate: David Hsieh| Summary:Two-dimensional Mott insulators host antiferromagnetic (AFM) correlations that are predicted to enhance the attractive interaction between empty (holons) and doubly occupied (doublons) sites, creating a novel pathway for exciton formation. However, experimental confirmation of this spin-mediated binding mechanism remains elusive. Leveraging the distinct magnetic critical properties of the Mott antiferromagnets Sr$_2$IrO$_4$ […]

The Emergence of Little Red Dots from Binary Massive Black Holes

Posted by klaurent Peking

Kavli Affiliate: Luis Ho | Summary:Little red dots (LRDs) are a newly identified class of broad-line active galactic nuclei (AGN) with a distinctive v-shape spectrum characterized by red optical and blue UV continuum emission. Their high abundance at redshifts of $zsim6-8$ and decline at lower redshifts suggest a transient origin. We propose that the spectral […]

SmartTrap: Automated Precision Experiments with Optical Tweezers

Posted by klaurent Berkeley

Kavli Affiliate: Carlos Bustamante | Summary:There is a trend in research towards more automation using smart systems powered by artificial intelligence. While experiments are often challenging to automate, they can greatly benefit from automation by reducing labor and increasing reproducibility. For example, optical tweezers are widely employed in single-molecule biophysics, cell biomechanics, and soft matter […]

From First Draft to Final Insight: A Multi-Agent Approach for Feedback Generation

Posted by dbos Peking

Kavli Affiliate: Xian Chen | First 5 Authors: Jie Cao, Chloe Qianhui Zhao, Xian Chen, Shuman Wang, Christian Schunn | Summary: Producing large volumes of high-quality, timely feedback poses significant challenges to instructors. To address this issue, automation technologies-particularly Large Language Models (LLMs)-show great potential. However, current LLM-based research still shows room for improvement in […]

Diverse and Flexible Strategies Enable Successful Cooperation in Marmoset Dyads

Posted by dbos Yale

Kavli Affiliate: Anirvan Nandy | Authors: Olivia C Meisner, Weikang Shi, Amrita Nair, Gargi Nandy, Monika P Jadi, Anirvan S Nandy and Steve W. C. Chang | Summary: In humans, cooperation relies on advanced social cognition, but the extent to which these mechanisms support cooperation in nonhuman primates remains unclear. To investigate this, we examined […]
