Kavli Affiliate: David W. Miller | Summary:Current language-guided 3D object placement typically predicts a rigid 6-DoF pose, ignoring the physical reality that indoor placements are dictated by contact. Consequently, predicted poses often float, interpenetrate supports, or fail to deform soft surfaces. We propose Deformable Contact-Aware Placement (DCAP), a framework that reframes placement as a drop-to-equilibrium […]
Kavli Affiliate: Wei Gao| Summary:We study equatorial timelike geodesics and associated gravitational-wave (GW) emission for a static Horndeski black hole with secondary scalar hair, characterized by an effective pressure parameter $p_mathrmeff$. Using the rational-orbit taxonomy $(z,w,v)$, we analyze the innermost stable circular orbit (ISCO), marginally bound orbit (MBO), and periodic bound orbits. We find that […]
Kavli Affiliate: David W. Miller | Summary:We present the first search for fixed-polarization dark photon (DP) dark matter in the 44-52$μmathrmeV$ mass range, corresponding to 10.7-12.5GHz. GigaBREAD is a room-temperature broadband dish antenna experiment in which DP convert to ordinary photons on a cylindrical metallic emission surface and are focused onto a radio-frequency receiver. Previous […]
Kavli Affiliate: Gerbrand Ceder| Summary:AI agents are playing an increasingly important role in physics research. However, existing physics benchmarks only evaluate fixed questions, isolated sub-tasks, or paper reproduction with given solutions, and rarely check research quality alongside correctness. We introduce FrontierPhysics, an end-to-end benchmark with 56 tasks made by 42 physicists based on their own […]
Kavli Affiliate: Kiyoshi Masui | Summary:Fast radio bursts (FRBs) are an emerging precision probe of cosmological fluctuations. The amount and quality of observed FRB data will grow enormously over the next decade. FRB dispersion data directly probe the free electron distribution up to intergalactic scales. Precision models of the free electron distribution are necessary to […]
Kavli Affiliate: Michael Turner | Summary:We respond to the recent paper by Efstathiou (arXiv:2607.29562) who makes several statements that appear to be in conflict with our recent paper (Turner & Huterer, arXiv:2606.05358). We stand by our primary result that direct determinations of $H_0$ can be sensitive to the late-time expansion history. We also point out […]
Kavli Affiliate: Xian Chen| Summary: We study (non-induced) subgraph counting under interactive local edge differential privacy (LEDP). Given a fixed pattern graph $H$ with $k$ vertices, $ellge1$ edges, and $q$ connected components, our goal is to approximately count its copies in an arbitrary $n$-vertex undirected graph while preserving edge privacy. We give two complementary accuracy […]
Kavli Affiliate: Mazhar Ali | Summary: We study the entanglement dynamics of two qutrits under collective dephasing for a family of states obtained by mixing a maximally entangled state that lives in the decoherence-free subspace with three nonstationary two-term states sharing a common amplitude ratio $r$. We obtain exact PPT and separability regions along the […]
Kavli Affiliate: Risa Wechsler | Summary:Small-scale galaxy clustering contains substantial cosmological information, but extracting it reliably requires robust modeling of the galaxy–halo connection. In this work, we compare two widely adopted families of empirical models, subhalo abundance matching (SHAM) and the halo occupation distribution (HOD), testing their predictions for galaxy clustering and their recovery of […]
Kavli Affiliate: Feng Long| Summary: This paper develops upper L-statistic methods for testing and localizing a high-dimensional mean change. At each candidate split, the proposed statistics rank the squared studentized CUSUM values across coordinates and aggregate either a fixed number or a fixed proportion of the largest entries. This construction connects max-type and sum-type procedures […]
