Predicting Consequences and Reinforcing Navigation Policies with Latent World Models

Posted by klaurent August 23, 2026Caltech

Kavli Affiliate: Wei Gao| Summary:World models enable agents to reason about future outcomes and learn policies from their knowledge of state transition, but existing approaches primarily focus on reconstructing future observations or features, which introduces unnecessary complexity and limits their effectiveness for decision making. In this work, we propose a compatibility prediction Latent World Model […]

Tools for Reducing Service Time in Near-Term Quantum Networks

Posted by klaurent August 21, 2026August 25, 2026Delft, This Week: Nanoscience

Kavli Affiliate: Stephanie Wehner | Summary:Architectures have been proposed to control entanglement generation in multi-user quantum networks. To allow time for local operations and classical communication at end nodes, these architectures insert fixed separations between consecutive batches of entanglement generation attempts. This reduces network utilization when attempts fail, leaving the network idle during the scheduled […]

EXPO: a quantum leap in fast, wide-band X-ray polarimetry for astrophysics

Posted by klaurent August 21, 2026August 25, 2026MIT, This Week: Astrophysics

Kavli Affiliate: Herman Marshall | Summary:The Enhanced X-ray Polarimetry Observatory (EXPO) is a mission concept proposed to ESA as an M8 candidate, with a prospective launch in 2041. Building on the scientific success of IXPE, EXPO is designed to overcome its two main limitations, the narrow 2-8 keV energy band and the very slow repointing […]

Pandora cluster Lensing, AGN, and Transient Exploration (PLATE) from JWST Multi-Epoch Imaging. I. Discovery of a type II supernova candidate in a spiral galaxy at $z=0.7$

Posted by klaurent August 21, 2026August 25, 2026Peking, This Week: Astrophysics

Kavli Affiliate: Subo Dong | Summary:We report the discovery and multi-wavelength analysis of a $zsim0.7$ transient PLATE-23a in the Abell 2744 field, as the first results of the Pandora Lensing, AGN, and Transient Exploration (PLATE) project. Using multi-epoch JWST NIRCam imaging spanning from 2022 to 2025, we detect PLATE-23a in 12 filters. Difference-imaging analysis reveals […]

Leveraging Impact Parameter to Mitigate the Transit Light Source Effect: Early Insights from TRAPPIST-1

Posted by klaurent August 20, 2026August 25, 2026MIT, This Week: Astrophysics

Kavli Affiliate: Sara Seager | Summary:Stellar activity complicates exoplanet transmission spectra, particularly for smaller planets around M dwarfs with JWST. The transit light source (TLS) effect, the imprinting of spectral differences between the average stellar disk and the occulted transit chord onto the transmission spectrum, makes it challenging to directly use the out-of-transit spectrum to […]

Strange Metal Hall Effect in Underdoped BaFe$_2$(As$_1-x$P$_x$)$_2$

Posted by klaurent August 20, 2026August 25, 2026Berkeley, This Week: Nanoscience

Kavli Affiliate: James Analytis| Summary:The unusual transport properties of strange metals point to the breakdown of the quasiparticle picture, the understanding of which remains one of the most vexing problems in physics. Here, we report investigations of the electrical Hall effect of the strange metal superconductor BaFe$_2$(As$_1-x$P$_x$)$_2$. We show that a doping-independent contribution to the […]
