Direct multi-model dark-matter search with gravitational-wave interferometers using data from the first part of the fourth LIGO-Virgo-KAGRA observing run

Posted by klaurent October 30, 2025Caltech

Kavli Affiliate: G. Ravichandran| First 5 Authors: [#item_custom_name[1, [#item_custom_name[2, [#item_custom_name[3, [#item_custom_name[4, [#item_custom_name[5| Summary:Gravitational-wave detectors can probe the existence of dark matter with exquisite sensitivity. Here, we perform a search for three kinds of dark matter — dilatons (spin-0), dark photons (spin-1) and tensor bosons (spin-2) — using three independent methods on the first part of […]

Thermoelectricity of moiré heavy fermions in MoTe2/WSe2 bilayers

Posted by klaurent October 30, 2025Cornell

Kavli Affiliate: Kinfai Mak | First 5 Authors: Yichi Zhang, Yichi Zhang, , , | Summary: Tunable Kondo lattice and heavy fermion physics have been recently reported in moiré materials, but most of the studies have focused on the electrical and magnetic properties. Quantitative thermoelectric measurements, which can reveal entropic information of the heavy fermions, […]

Metallicity Gradients in Modern Cosmological Simulations II: The Role of Bursty Versus Smooth Feedback at High-Redshift

Posted by klaurent October 30, 2025MIT

Kavli Affiliate: Mark Vogelsberger | Summary:The distribution of gas-phase metals within galaxies encodes the impact of stellar feedback on galactic evolution. At high-redshift, when galaxies are rapidly assembling, feedback-driven outflows and turbulence can strongly reshape radial metallicity gradients. In this work, we use the FIRE-2, SPICE, Thesan and Thesan Zoom cosmological simulations — spanning a […]

Kimi Linear: An Expressive, Efficient Attention Architecture

Posted by klaurent October 30, 2025November 10, 2025Berkeley

Kavli Affiliate: Feng Wang | First 5 Authors: Kimi Team, Kimi Team, , , | Summary: We introduce Kimi Linear, a hybrid linear attention architecture that, for the first time, outperforms full attention under fair comparisons across various scenarios — including short-context, long-context, and reinforcement learning (RL) scaling regimes. At its core lies Kimi Delta […]
