     Magnon squeezing in the quantum regime

     Weng, Yuan-Chao; Xu, Da; Chen, Zhen et al.

     arXiv · 2026 · English · arXiv

     Squeezed states, crucial for quantum metrology and emerging quantum technologies, have been demonstrated in various platforms, but quantum squeezing of magnons in macroscopic spin systems remains elusive. Here we report the experimental observation of quantum-level magnon squeezing in a…

     Uncertainty Quantification in Data-Driven Dynamical Models via Inverse Problem Solving

     Akrout, Mohamed; Wilson, Dan

     arXiv · 2026 · English · arXiv

     Data-driven model identification strategies can be used to obtain phenomenological models that capture the temporal evolution of observable data. While it is usually straightforward to obtain such a model from time series data, for instance with least-squares fitting, it is generally difficult to…

     Revisiting CPL with sign-switching density: To cross or not to cross the NECB

     Gökçen, Mine; Akarsu, Özgür; Di Valentino, Eleonora

     arXiv · 2026 · English · arXiv

     Recent DESI DR2 BAO measurements, when combined with CMB and SNeIa data, exhibit a $3.2σ$-$3.4σ$ preference for dynamical dark energy (DE) described by the CPL-parametrized equation of state. A particularly striking feature of these reconstructions is an apparent transition from an early-time…

     DiffBMP: Differentiable Rendering with Bitmap Primitives

     Hong, Seongmin; Kim, Junghun James; Kim, Daehyeop et al.

     arXiv · 2026 · English · arXiv

     We introduce DiffBMP, a scalable and efficient differentiable rendering engine for a collection of bitmap images. Our work addresses a limitation that traditional differentiable renderers are constrained to vector graphics, given that most images in the world are bitmaps. Our core contribution is a…

     Huang, Xun; Qin, Simeng; Jia, Xiaoshuang et al.

     arXiv · 2026 · English · arXiv

     As Large Language Models (LLMs) are increasingly used, their security risks have drawn increasing attention. Existing research reveals that LLMs are highly susceptible to jailbreak attacks, with effectiveness varying across language contexts. This paper investigates the role of classical Chinese in…

     WISER: Wider Search, Deeper Thinking, and Adaptive Fusion for Training-Free Zero-Shot Composed Image Retrieval

     Wang, Tianyue; Qu, Leigang; Yang, Tianyu et al.

     arXiv · 2026 · English · arXiv

     Zero-Shot Composed Image Retrieval (ZS-CIR) aims to retrieve target images given a multimodal query (comprising a reference image and a modification text), without training on annotated triplets. Existing methods typically convert the multimodal query into a single modality-either as an edited…

     CXReasonAgent: Evidence-Grounded Diagnostic Reasoning Agent for Chest X-rays

     Lee, Hyungyung; Yoon, Hangyul; Choi, Edward

     arXiv · 2026 · English · arXiv

     Chest X-ray plays a central role in thoracic diagnosis, and its interpretation inherently requires multi-step, evidence-grounded reasoning. However, large vision-language models (LVLMs) often generate plausible responses that are not faithfully grounded in diagnostic evidence and provide limited…

     Hole Phenomenon of Gaussian Analytic Functions with Power-exponential Weights

     Du, Yun-Heng

     arXiv · 2026 · English · arXiv

     We establish the \emph{hole phenomenon} for the Gaussian analytic function \[ F_β(z)=\sum_{n=0}^{\infty}\frac{ξ_{n}}{\sqrt{Γ\bigl(\frac{2}β(n+1)\bigr)}}\,z^{n}, \] associated with the power-exponential weight $e^{-|z|^β}$ on $\mathbb{C}$, where $β>0$. Under the condition that $F_β(z)$ has no zeros…

     Spacetime in motion: an evolving relativistic binary black hole metric for GIZMO

     Fedrigo, Giacomo; Lupi, Alessandro; Franchini, Alessia et al.

     arXiv · 2026 · English · arXiv

     The last evolutionary stages of massive black hole binaries prior to coalescence is dominated by the emission of gravitational waves, which will be probed by the future Laser Interferometer Space Antenna. If gas is present around the two black holes, however, the associated electromagnetic emission…

     The impact of strong lensing on Hubble constant measurements with gravitational-wave dark sirens

     Seo, Eungwang; Kim, Kyungmin; Li, Zhuotao et al.

     arXiv · 2026 · English · arXiv

     The disagreement between early and late Universe electromagnetic measurements of the Hubble constant, $H_0$, known as the Hubble tension, highlights the need for independent and complementary probes. Gravitational-wave events have recently emerged as such a probe for constraining cosmological…

     KDFlow: A User-Friendly and Efficient Knowledge Distillation Framework for Large Language Models

     Zhang, Songming; Zhang, Xue; Zhang, Tong et al.

     arXiv · 2026 · English · arXiv

     Knowledge distillation (KD) is an essential technique to compress large language models (LLMs) into smaller ones. However, despite the distinct roles of the student model and the teacher model in KD, most existing frameworks still use a homogeneous training backend (e.g., FSDP and DeepSpeed) for…

     Bridging the Prandtl number gap: 3D simulations of thermohaline convection in astrophysical regimes

     Fraser, Adrian E.

     arXiv · 2026 · English · arXiv

     Thermohaline convection (also known as fingering convection or thermohaline mixing) occurs in stellar radiation zones where a sufficient inversion of the mean molecular weight is present. This process mixes chemicals radially and occurs in a variety of stars, including near the luminosity bump on…

     The contribution of nitrogen Frenkel-pair formation to the high-temperature heat capacity of uranium mononitride

     AbdulHameed, Mohamed; Beeler, Benjamin

     arXiv · 2026 · English · arXiv

     The high-temperature heat capacity of uranium mononitride (UN) remains uncertain due to conflicting measurements and models above ~1700 K. To assess whether intrinsic defect formation contributes to the observed superlinear behavior of $C_P(T)$, we perform large-scale molecular dynamics simulations…

     arXiv · 2026 · English · arXiv

     Coverage closure is a critical requirement in Integrated Chip (IC) development process and key metric for verification sign-off. However, traditional exhaustive approaches often fail to achieve full coverage within project timelines. This study presents an agentic AI-driven workflow that utilizes…

     Wu, Wenhao; Tang, Zhentao; Li, Yafu et al.

     arXiv · 2026 · English · arXiv

     Large Language Models (LLMs) exhibit high reasoning capacity in medical question-answering, but their tendency to produce hallucinations and outdated knowledge poses critical risks in healthcare fields. While Retrieval-Augmented Generation (RAG) mitigates these issues, existing methods rely on…

     Benchmarking pre-main sequence stellar evolutionary tracks using disk-based dynamical stellar masses

     Zallio, Luigi; Vioque, Miguel; Andrews, Sean M. et al.

     arXiv · 2026 · English · arXiv

     Stellar masses are a fundamental property to understand models of pre-main sequence evolution, but their values derived from Hertzsprung-Russell (HR) diagrams are strongly model dependent. We benchmark pre-main sequence stellar evolutionary tracks using stellar masses dynamically estimated by…

     Relaxation to nonequilibrium

     Maes, Christian; Netočný, Karel

     arXiv · 2026 · English · arXiv

     We describe the structure of relaxation for a steadily driven macroscopic body. The time-evolution is characterized as the zero-cost flow for a nonequilibrium and nonlinear extension of the Onsager-Machlup action governing the dynamical fluctuations. The approach hinges on two main elements: the…

     Alfvén wave propagation in the partially ionized lower solar atmosphere: a test of the single-fluid approximation

     Soler, Roberto

     arXiv · 2026 · English · arXiv

     Alfvén waves are widely believed to play an important role in the transport of energy from the solar photosphere to the corona through the partially ionized chromosphere. In previous work, the properties of torsional Alfvén waves were theoretically studied using a multi-fluid model. Here, we…

     Coexistence of Chromatic Flares and an Achromatic QPO in the Gamma-ray Blazar PG 1553+113

     Madero, Elena; Domínguez, Alberto

     arXiv · 2026 · English · arXiv

     The physical origin of quasi-periodic oscillations (QPOs) in blazars remains debated, with geometric and plasma-driven scenarios as the main competing interpretations. Discriminating between them requires probing variability beyond flux periodicity. We study the spectral evolution of the BL Lac…
