Agentic LLM Reasoning in a Self-Driving Laboratory for Air-Sensitive Lithium Halide Spinel Conductors

Posted by klaurent April 13, 2026April 27, 2026Berkeley

Kavli Affiliate: Gerbrand Ceder| Summary:Self-driving laboratories promise to accelerate materials discovery. Yet current automated solid-state synthesis platforms are limited to ambient conditions, thereby precluding their use for air-sensitive materials. Here, we present A-Lab for Glovebox Powder Solid-state Synthesis (A-Lab GPSS), a robotic platform capable of synthesizing and characterizing air-sensitive inorganic materials under strict air-free conditions.

A Forward, Analytic, Differentiable, Geometric (But Inflexible) Lens Model

Posted by klaurent April 13, 2026April 27, 2026MIT

Kavli Affiliate: Paul Schechter | Summary:We anticipate that hundreds of thousands of distant, strongly gravitationally lensed sources will be detectable with the European Space Agency’s (ESA) Euclid mission and the Rubin Observatory Legacy Survey of Space and Time. We consider the virtues and shortcomings of the Singular Isothermal Elliptical Potential (SIEP) with Parallel External Shear […]

Intense and extended CIII] emission suggests a strong outflow in JADES-GS-z14-0

Posted by klaurent April 13, 2026April 27, 2026Cambridge

Kavli Affiliate: Roberto Maiolino | Summary:JWST has revealed an overabundance of very bright, blue galaxies at z>10, raising fundamental questions about how star formation and feedback operate at Cosmic Dawn. We present new JWST/NIRSpec MSA PRISM/CLEAR spectroscopy of JADES-GS-z14-0 (z=14.18) obtained with the JADES and OASIS programmes. While the rest-frame UV continuum flux level and […]

Classification and correlation signatures of chiral spin liquids on the pyrochlore lattice

Posted by klaurent April 13, 2026UCSB

Kavli Affiliate: Leon Balents | Summary:We present a systematic classification and variational study of chiral quantum spin liquids on the pyrochlore lattice based on fermionic parton constructions. Focusing on chiral $mathrmU(1)$ and $mathbbZ_2$ spin-liquid Ansätze, we characterize their symmetry properties, flux structures, and low-energy spinon spectra within a projective symmetry group framework, and incorporate gauge […]

Impact of Stochastic Pop~III X-ray Binaries on the Cosmological 21-cm Signal

Posted by klaurent April 13, 2026April 27, 2026Cambridge

Kavli Affiliate: George Efstathiou | Summary:High-mass X-ray binaries are one of the primary drivers of the 21-cm signal from Cosmic Dawn and Reionization, playing a leading role in the thermal history of the intergalactic medium. In traditional semi-numerical simulations, a deterministic scaling relation between the total X-ray luminosity of high-mass X-ray binaries, $L_rm X$, and […]
