Kavli Affiliate: Frank Wilczek | Summary:We estimate the degree of squeezing possible in gravitational waves due to nonlinear gravitational effects in the weakly perturbative regime. Using the predicted amplitude ratios for higher harmonic generation in the ringdown phase of a black hole merger event, we estimate the relevant degree of squeezing produced by a Schwarzschild […]
Kavli Affiliate: Frank Wilczek | 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 Query: search_query=au:”Wilczek Frank”&id_list=&start=0&max_results=10Read More
Kavli Affiliate: Frank Wilczek | 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 in number or phase, can be revealed through appropriate detection strategies. | Search […]
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 | 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 Symphony suite with the Nimbus "star-tagging" model of the stellar halo […]

Orofacial clefting […]
Kavli Affiliate: Jie Shan | First 5 Authors: Yiyu Xia, Yiyu Xia, , , | Summary: The emergence of high transition temperature (Tc) superconductivity in strongly correlated materials remains a major unsolved problem in physics. High-Tc materials, such as cuprates, are generally complex and not easily tunable, making theoretical modelling difficult. Although the Hubbard model–a […]
Kavli Affiliate: Chiara Daraio | Summary:Molecular crystal structure prediction (CSP) is essential for applications in pharmaceuticals and organic electronics. However, CSP remains challenging and computationally intensive due to the need to explore a large search space with sub-kJ/mol accuracy to distinguish between competing polymorphs. While dispersion-inclusive density functional theory (DFT) offers the necessary precision, its […]
