Kavli Affiliate: Feng Wang | First 5 Authors: Gang Cheng, Gang Cheng, , , | Summary: We introduce Wan-Animate, a unified framework for character animation and replacement. Given a character image and a reference video, Wan-Animate can animate the character by precisely replicating the expressions and movements of the character in the video to generate […]
Kavli Affiliate: Rana X. Adhikari | First 5 Authors: , , , , | Summary: Improved low-frequency sensitivity of gravitational wave observatories would unlock study of intermediate-mass black hole mergers, binary black hole eccentricity, and provide early warnings for multi-messenger observations of binary neutron star mergers. Today’s mirror stabilization control injects harmful noise, constituting a […]

Kavli Affiliate: Xiang Zhang | First 5 Authors: Zhi-Peng Jia, Zhi-Peng Jia, , , | Summary: We report a systematic uncertainty of $9.2times 10^-19$ for the USTC Sr1 optical lattice clock, achieving accuracy at the level required for the roadmap of the redefinition of the SI second. A finite-element model with it in situ-validated, spatially-resolved […]
Kavli Affiliate: Chris Xu | First 5 Authors: The bbchallenge Collaboration, The bbchallenge Collaboration, , , | Summary: We prove that $S(5) = 47,176,870$ using the Coq proof assistant. The Busy Beaver value $S(n)$ is the maximum number of steps that an $n$-state 2-symbol Turing machine can perform from the all-zero tape before halting, and […]
Kavli Affiliate: Eliska Greplova | First 5 Authors: Thomas Spriggs, Thomas Spriggs, , , | Summary: We present a neural network wavefunction framework for solving non-Abelian lattice gauge theories in a continuous group representation. Using a combination of $SU(2)$ equivariant neural networks alongside an $SU(2)$ invariant, physics-inspired ansatz, we learn a parameterization of the ground […]
Kavli Affiliate: Lihong V. Wang | First 5 Authors: Lihong V. Wang, Lihong V. Wang, , , | Summary: We present a geometric interpretation of the hyperfine Breit–Rabi eigenvalues and eigenvectors in alkali atoms after reformulating the standard solution into a compact form. In this picture, the nuclear magnetic moment has a polar angle fixed […]
Kavli Affiliate: David A. Muller | First 5 Authors: Felix Bennemann, Felix Bennemann, , , | Summary: High-resolution transmission electron microscopy (HRTEM) is an important method for imaging beam sensitive materials often under cryo conditions. Electron ptychography in the scanning transmission electron microscope (STEM) has been shown to reconstruct low-noise phase data at a reduced […]
Kavli Affiliate: David Charbonneau | First 5 Authors: Samuel W. Yee, Samuel W. Yee, , , | Summary: The “Neptunian ridge” is a recently identified peak in the frequency of planets with sizes between that of Neptune and Saturn orbiting their host stars with periods between 3 and 6 days (A. Castro-Gonz’alez et al. 2024). […]
Kavli Affiliate: Wei Gao | First 5 Authors: Ziye Deng, Ziye Deng, , , | Summary: Molecular dynamics simulations using a Gaussian Approximation Potential (GAP) reveal a stress triaxiality driven, two-step Si-I (diamond cubic) to Si-V (simple hexagonal) phase transition pathway in a spherical Si nanoparticle with a 10 nm diameter under triaxial compression.
