Kitaev-derived Gapless Spin Liquid in the $K$-$J$-$Γ$-$Γ’$ Quantum Magnet Na$_2$Co$_2$TeO$_6$

Kavli Affiliate: Gang Su | First 5 Authors: Han Li, Han Li, , , | Summary: The realization of quantum spin liquids (QSLs) in Kitaev magnets represents an intriguing topic in frustrated quantum magnetism. Despite prediction in the pure Kitaev honeycomb model, realization of QSLs in realistic systems and materials remain scarce. The recent discovery […]

Parity Violation in Galaxy Shapes: Primordial Non-Gaussianity

Kavli Affiliate: Eiichiro Komatsu | Summary:We present a comprehensive study of galaxy intrinsic alignment (IA) as a probe of parity-violating primordial non-Gaussianity (PNG). Within the effective field theory (EFT) framework, we show that the parity-odd IA power spectrum is sensitive to the collapsed limit of the parity-odd primordial trispectrum. For a $U(1)$-gauge inflationary model, the […]

Release and Recapture of Silica Nanoparticles from an Optical Trap in Weightlessness

Kavli Affiliate: Sven Herrmann | Summary:Optically trapped Silica nanoparticles are a promising tool for precise sensing of gravitational or inertial forces and fundamental physics, including tests of quantum mechanics at ‘large’ mass scales. This field, called levitated optomechanics can greatly benefit from an application in weightlessness. In this paper we demonstrate the feasibility of such […]

Memorization in Large Language Models in Medicine: Prevalence, Characteristics, and Implications

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:Large Language Models (LLMs) have demonstrated significant potential in medicine, with many studies adapting them through continued pre-training or fine-tuning on medical data to enhance domain-specific accuracy and safety. However, a key open question remains: to what extent do LLMs memorize medical […]

Ground-Based Mid-IR Direct Imaging: The Origin of the Thermal Background on the Keck II Telescope and Correcting Instrumental Systematics

Kavli Affiliate: Bruce Macintosh | Summary:Mid-IR wavelengths are of particular interest to exoplanet science due to the fact they can extend the searchable parameter space to planets that are older and/or colder. However, a significant source of uncertainty at mid-IR wavelengths on ground-based telescopes is the thermal background. This background comes from blackbody radiation in […]

Dynamical Quantum Multigraphs

Kavli Affiliate: Nathan Lewis | Summary:Motivated by applications in background-independent quantum gravity, we discuss the quantization of labeled and unlabeled finite multigraphs with a maximum edge count. We provide a unified way to represent quantum multigraphs with labeled or unlabeled vertices, which enables the study of quantum multigraphs as dynamical microscopic degrees of freedom and […]
