Kavli Affiliate: Masahito Yamazaki | First 5 Authors: Jun-ichi Sakamoto, Jun-ichi Sakamoto, , , | Summary: The four-dimensional Chern-Simons (CS) theory provides a systematic procedure for realizing two-dimensional integrable field theories. It is therefore a natural question to ask whether integrable deformations of the theories can be realized in the four-dimensional CS theory. In this […]

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: Eric Miller | First 5 Authors: Xi Long, Xi Long, , , | Summary: We present results from the Chandra X-ray Observatory Large Project (878 ks in 28 observations) of the Large Magellanic Cloud supernova remnant N132D. We measure the expansion of the forward shock in the bright southern rim to be $0.!^primeprime10 […]
Kavli Affiliate: David A. Muller | First 5 Authors: Felix Bennemann, Felix Bennemann, , , | Summary: High-resolution transmission electron microscopy (HRTEM) is an important method for imaging beam sensitive materials often under cryo conditions. Electron ptychography in the scanning transmission electron microscope (STEM) has been shown to reconstruct low-noise phase data at a reduced […]
Kavli Affiliate: Laura Schaefer | First 5 Authors: Lichang Zhu, Lichang Zhu, , , | Summary: Predicting and interpreting thermal performance under oscillating flow in porous structures remains a critical challenge due to the complex coupling between fluid dynamics and geometric features. This study introduces a data-driven wGAN-LBM-Nested_CV framework that integrates generative deep learning, numerical […]
Kavli Affiliate: David Charbonneau | First 5 Authors: Samuel W. Yee, Samuel W. Yee, , , | Summary: The “Neptunian ridge” is a recently identified peak in the frequency of planets with sizes between that of Neptune and Saturn orbiting their host stars with periods between 3 and 6 days (A. Castro-Gonz’alez et al. 2024). […]
Kavli Affiliate: Lile Wang | First 5 Authors: Shuting Lin, Shuting Lin, , , | Summary: We report the discovery of a dense molecular ring-like structure in a dense (10$^5$ cm$^-3$), cold (pc-scale CO depletion at a factor of 5), and young (10$^4$ year) star-forming region G34.74-0.12, revealed by C$^18$O (2-1), HNC (1-0), and N$_2$H$^+$ […]
Kavli Affiliate: Michael Shadlen | Authors: Prayshita Sharma, Michael Shadlen and S Shushruth | Summary: Perceptual decision-making refers to the class of decisions in which sensory evidence is used to categorize percepts and guide actions. Conventionally, categorical decisions are thought to precede motor actions. However, recent studies in nonhuman primates challenge this assumption — when […]
Kavli Affiliate: Zhuo Li | First 5 Authors: Yechen Zhang, Yechen Zhang, , , | Summary: Reinforcement learning (RL) has shown promise in a large number of robotic control tasks. Nevertheless, its deployment on unmanned aerial vehicles (UAVs) remains challenging, mainly because of reliance on accurate dynamic models and platform-specific sensing, which hinders cross-platform transfer.
