Kavli Affiliate: Jing Wang | First 5 Authors: Cong-han Wang, Cong-han Wang, , , | Summary: A nonlocal version of the massive Thirring model (MTM) and its solutions are presented. We start from a 4-component system that can be reduced to the classical MTM and nonlocal MTM. Bilinear form of the 4-component system and general […]
Kavli Affiliate: David P. Huenemoerder | First 5 Authors: Sean J. Gunderson, Sean J. Gunderson, , , | Summary: We present the first first X-ray polarization measurements of a white dwarf, the intermediate polar EX Hya. We measured significant polarization only in the 2 — 3 keV energy band with a polarization degree of 8 […]

Kavli Affiliate: Wei Gao | First 5 Authors: Fei Shuang, Fei Shuang, , , | Summary: Machine learning interatomic potentials (MLIPs) enable accurate atomistic modelling, but reliable uncertainty quantification (UQ) remains elusive. In this study, we investigate two UQ strategies, ensemble learning and D-optimality, within the atomic cluster expansion framework. It is revealed that higher […]
Kavli Affiliate: Frank Wilczek | First 5 Authors: Sreenath K. Manikandan, Sreenath K. Manikandan, , , | Summary: We demonstrate that long-lived black hole quasi-normal modes become quantum mechanically squeezed due to nonlinear gravitational effects. We estimate the degree of squeezing for the fundamental mode of a Schwarzschild black hole quantitatively. | Search Query: ArXiv […]
Kavli Affiliate: Frank Wilczek | First 5 Authors: Sreenath K. Manikandan, Sreenath K. Manikandan, , , | Summary: We discuss the statistics of correlations between two resonant detectors. We show that this allows simple null tests of the coherent state hypothesis, free of vacuum (quantum) noise. Complementary aspects of the radiation field, {it e.g.}, squeezing […]
Kavli Affiliate: Jing Wang | First 5 Authors: Wentao Qu, Wentao Qu, , , | Summary: Denoising Diffusion Probabilistic Models (DDPMs) have shown success in robust 3D object detection tasks. Existing methods often rely on the score matching from 3D boxes or pre-trained diffusion priors. However, they typically require multi-step iterations in inference, which limits […]
Kavli Affiliate: Zheng Zhu | First 5 Authors: , , , , | Summary: We report a magnetic imaging method using atomic force microscopy to measure the locally induced anomalous Nernst effect. The tip contact creates a local temperature gradient on the sample surface controlled by a neighboring Joule heating wire. We demonstrate the imaging […]

Kavli Affiliate: Risa Wechsler | First 5 Authors: Tara Dacunha, Tara Dacunha, , , | Summary: The diffuse starlight extending throughout massive galaxy clusters, known as intracluster light (ICL), has the potential to be read as a memoir of mass accretion: informative, individual, and yet imperfect. Here, we combine dark matter-only zoom-in simulations from the […]
