Nanocrystal Geometry Governs Phase Transformation Pathways in Palladium Hydride

Posted by klaurent December 31, 2025Berkeley

Kavli Affiliate: David T. Limmer | Summary:Pathways and structural dynamics of phase transformations impact performance of materials in energy and information storage technologies. Palladium hydride ($mathrmPdH_x$) nanocrystals are an ideal model system for studying solute-induced phase transformations, where elastic energy from lattice mismatch between $α$-$mathrmPdH_x$ and $β$-$mathrmPdH_x$ phases is often considered a key to determining […]

Automated electrostatic characterization of quantum dot devices in single- and bilayer heterostructures

Posted by klaurent December 31, 2025Delft

Kavli Affiliate: Menno Veldhorst | Summary:As quantum dot (QD)-based spin qubits advance toward larger, more complex device architectures, rapid, automated device characterization and data analysis tools become critical. The orientation and spacing of transition lines in a charge stability diagram (CSD) contain a fingerprint of a QD device’s capacitive environment, making these measurements useful tools […]

A free-floating-planet microlensing event caused by a Saturn-mass object

Posted by klaurent December 31, 2025Peking

Kavli Affiliate: Subo Dong | Summary:A population of free-floating planets is known from gravitational microlensing surveys. None have a directly measured mass, owing to a degeneracy with the distance, but the population statistics indicate that many are less massive than Jupiter. We report a microlensing event — KMT-2024-BLG-0792/OGLE-2024-BLG-0516, which was observed from both ground- and […]

Feeling Blue: Constructing a Robust SALT3 UV Template and Constraining its Redshift Dependency

Posted by klaurent December 31, 2025Chicago

Kavli Affiliate: Richard Kessler | Summary:Upcoming cosmological surveys will obtain numerous rest-frame ultraviolet (UV) observations of Type Ia supernovae (SNe Ia), yet there is concern about how standardizable SNe Ia are in the UV. In this work, we train a robust optical–UV SED model for SNe Ia (SALT3-UV) with the open-source model-training software $textttSALTshaker$. We […]

Rescuing Neurodevelopmental Deficits in AMPA Receptor Gain-of-Function Mutant

Posted by dbos December 31, 2025January 12, 2026Hopkins

Kavli Affiliate: Richard Huganir | Authors: Chih-Ming Chen, Yu-Min Huang, Chih-Ching Chung, Richard C. Johnson, Cheng-Ya Tsai, Yu-Han Chen, Han L. Tan, Fu-Yun Hsiao, Richard L. Huganir and Shu-Ling Chiu | Summary: AMPA receptors (AMPARs) mediate fast excitatory synaptic transmission and are essential for neuronal development and brain function. We investigated the role of a […]

The least prime with a given cycle type

Posted by klaurent December 31, 2025February 17, 2026Stanford

Kavli Affiliate: Hsiao-Mei (Sherry) Cho| First 5 Authors: [#item_custom_name[1, [#item_custom_name[2, [#item_custom_name[3, [#item_custom_name[4, [#item_custom_name[5| Summary:Let $G$ be a finite group. Let $K/k$ be a Galois extension of number fields with Galois group isomorphic to $G$, and let $C subseteq mathrmGal(K/k) simeq G$ be a conjugacy invariant subset. It is well known that there exists an unramified […]

Towards autonomous time-calibration of large quantum-dot devices: Detection, real-time feedback, and noise spectroscopy

Posted by klaurent December 31, 2025Delft

Kavli Affiliate: Menno Veldhorst | Summary:The performance and scalability of semiconductor quantum-dot (QD) qubits are limited by electrostatic drift and charge noise that shift operating points and destabilize qubit parameters. As systems expand to large one- and two-dimensional arrays, manual recalibration becomes impractical, creating a need for autonomous stabilization frameworks. Here, we introduce a method […]

Exact Identity Linking Entropy Production and Mutual Information

Posted by klaurent December 31, 2025February 17, 2026Stanford

Kavli Affiliate: Hsiao-Mei (Sherry) Cho| First 5 Authors: [#item_custom_name[1, [#item_custom_name[2, [#item_custom_name[3, [#item_custom_name[4, [#item_custom_name[5| Summary:Linking entropy production (EP) to information is a key step toward data-driven nonequilibrium thermodynamics. We derive an exact identity for overdamped Langevin dynamics that equates the total EP rate to the mutual-information rate between an infinitesimal displacement and its time-symmetric midpoint, up […]

Let It Flow: Agentic Crafting on Rock and Roll, Building the ROME Model within an Open Agentic Learning Ecosystem

Posted by klaurent December 31, 2025Caltech

Kavli Affiliate: Wei Gao| Summary:Agentic crafting requires LLMs to operate in real-world environments over multiple turns by taking actions, observing outcomes, and iteratively refining artifacts. Despite its importance, the open-source community lacks a principled, end-to-end ecosystem to streamline agent development. We introduce the Agentic Learning Ecosystem (ALE), a foundational infrastructure that optimizes the production pipeline […]

Heat kernel estimates for Markov processes with jump kernels blowing-up at the boundary

Posted by klaurent December 31, 2025February 17, 2026Stanford

Kavli Affiliate: Hsiao-Mei (Sherry) Cho| First 5 Authors: [#item_custom_name[1, [#item_custom_name[2, [#item_custom_name[3, [#item_custom_name[4, [#item_custom_name[5| Summary:In this paper, we study purely discontinuous symmetric Markov processes on closed subsets of $mathbb R^d$, $dge 1$, with jump kernels of the form $J(x,y)=|x-y|^-d-αmathcal B(x,y)$, $αin (0,2)$, where the function $mathcal B(x,y)$ may blow up at the boundary of the state […]
