Sensitivity of an Early Dark Matter Search using the Electromagnetic Calorimeter as a Target for the Light Dark Matter eXperiment

Posted by klaurent August 11, 2025Chicago

Kavli Affiliate: Gordan Krnjaic| First 5 Authors: LDMX Collaboration, LDMX Collaboration, , , | Summary:The Light Dark Matter eXperiment (LDMX) is proposed to employ a thin tungsten target and a multi-GeV electron beam to carry out a missing momentum search for the production of dark matter candidate particles. We study the sensitivity for a complementary […]

WideSearch: Benchmarking Agentic Broad Info-Seeking

Posted by klaurent August 11, 2025Peking

Kavli Affiliate: Ke Wang | First 5 Authors: Ryan Wong, Ryan Wong, , , | Summary: From professional research to everyday planning, many tasks are bottlenecked by wide-scale information seeking, which is more repetitive than cognitively complex. With the rapid development of Large Language Models (LLMs), automated search agents powered by LLMs offer a promising […]

DIVER: A Multi-Stage Approach for Reasoning-intensive Information Retrieval

Posted by klaurent August 11, 2025Cornell

Kavli Affiliate: Dan Luo | First 5 Authors: Meixiu Long, Meixiu Long, , , | Summary: Retrieval-augmented generation has achieved strong performance on knowledge-intensive tasks where query-document relevance can be identified through direct lexical or semantic matches. However, many real-world queries involve abstract reasoning, analogical thinking, or multi-step inference, which existing retrievers often struggle to […]

Time Ordering Effects and Destruction of Quasiparticles in Two-dimensional Holographic CFTs

Posted by klaurent August 11, 2025UCAS

Kavli Affiliate: Masahiro Nozaki | Summary:In this paper, we investigate the entanglement dynamics induced by a composite operator, defined as the local operator evolved with the time evolution operator constructed of the Euclidean and Lorentzian ones. The systems under consideration are described by two-dimensional holographic conformal field theories (2d holographic CFTs), the theories described by […]

Circuit inhibition promotes the dynamic reorganization of prefrontal task encoding to support cognitive flexibility

Posted by dbos August 10, 2025August 25, 2025UCSF

Kavli Affiliate: Vikaas Sohal | Authors: Carlos Johnson-Cruz, Kathleen K.A. Cho and Vikaas S. Sohal | Summary: The mammalian prefrontal cortex encodes variables related to goal-directed behavior, and enables flexibility during environmental changes, making it critical to understand how the dynamic updating vs. stable maintenance of different encodings contribute to behavioral adaptation. We addressed this […]

Intercalation-Induced Near Room-Temperature Ferromagnetism in CrI3 via Synergistic Exchange Pathways

Posted by klaurent August 10, 2025UCAS

Kavli Affiliate: Gang Su | First 5 Authors: Qing-Han Yang, Qing-Han Yang, , , | Summary: The development of room-temperature magnetic semiconductors is critical for advancing spintronic technologies, yet van der Waals magnets like CrI3 exhibit intrinsically low Curie temperatures (Tc = 45 K). This study employs first-principles calculations to demonstrate that atom intercalation, particularly […]

Ferroelectric switching of interfacial dipoles in $α$-RuCl$_3$/graphene heterostructure

Posted by klaurent August 10, 2025Caltech

Kavli Affiliate: Joseph Falson | Summary:We demonstrate electrically switchable, non-volatile dipoles in graphene/thin hBN/$α$-RuCl$_3$ heterostructures, stabilized purely by interfacial charge transfer across an atomically thin dielectric barrier. This mechanism requires no sliding or twisting to explicitly break inversion symmetry and produces robust ferroelectric-like hysteresis loops that emerge prominently near 30~K. Systematic measurements under strong in-plane […]
