Broadband and high-precision two-level system loss measurement using superconducting multi-wave resonators

Posted by klaurent Caltech

Kavli Affiliate: Oskar Painter | Summary:Two-level systems (TLS) are known to be a dominant source of dissipation and decoherence in superconducting qubits. Superconducting resonators provide a convenient way to study TLS-induced loss due to easier design and fabrication in comparison to devices that include non-linear elements. However, accurately measuring TLS-induced loss in a resonator in […]

Sharp spectroscopic fingerprints of disorder in an incompressible magnetic state

Posted by dbos UCAS

Kavli Affiliate: Cheng Peng | First 5 Authors: Chaebin Kim, Sumedh Rathi, Naipeng Zhang, Arnab Seth, Nikolai V. Simonov | Summary: Disorder significantly impacts the electronic properties of conducting quantum materials by inducing electron localization and thus altering the local density of states and electric transport. In insulating quantum magnetic materials the effects of disorder […]

HeuriGym: An Agentic Benchmark for LLM-Crafted Heuristics in Combinatorial Optimization

Posted by klaurent Peking

Kavli Affiliate: Li Xin Li| First 5 Authors: [#item_custom_name[1, [#item_custom_name[2, [#item_custom_name[3, [#item_custom_name[4, [#item_custom_name[5| Summary:While Large Language Models (LLMs) have demonstrated significant advancements in reasoning and agent-based problem-solving, current evaluation methodologies fail to adequately assess their capabilities: existing benchmarks either rely on closed-ended questions prone to saturation and memorization, or subjective comparisons that lack consistency and […]

A transiting giant planet in orbit around a 0.2-solar-mass host star

Posted by klaurent MIT

Kavli Affiliate: Alan Levine | Summary:Planet formation models suggest that the formation of giant planets is significantly harder around low-mass stars, due to the scaling of protoplanetary disc masses with stellar mass. The discovery of giant planets orbiting such low-mass stars thus imposes strong constraints on giant planet formation processes. Here, we report the discovery […]

MEMOIR: Lifelong Model Editing with Minimal Overwrite and Informed Retention for LLMs

Posted by klaurent Peking

Kavli Affiliate: Ke Wang | First 5 Authors: Ke Wang, Ke Wang, , , | Summary: Language models deployed in real-world systems often require post-hoc updates to incorporate new or corrected knowledge. However, editing such models efficiently and reliably-without retraining or forgetting previous information-remains a major challenge. Existing methods for lifelong model editing either compromise […]

JIP4 deficiency causes a novel lysosome storage disease arising from impaired cystine efflux

Posted by dbos Yale

Kavli Affiliate: Shawn Ferguson | Authors: Layla M Nassar, xiaojian Shi, Agnes Roczniak-Ferguson, Hongying Shen and Shawn M Ferguson | Summary: Lysosomes break down macromolecules, clear cellular waste and recycle nutrients such as cystine. We describe a novel mechanism whereby JIP4 regulates lysosomal cystine storage by controlling the abundance of cystinosin (CTNS), the transporter responsible […]
