Kavli Affiliate: Risa Wechsler | First 5 Authors: Catherine E. Fielder, Yao-Yuan Mao, Andrew R. Zentner, Jeffrey A. Newman, Hao-Yi Wu | Summary: Cold dark matter haloes consist of a relatively smooth dark matter component as well as a system of bound subhaloes. It is the prevailing practice to include all halo mass, including mass […]
Kavli Affiliate: Boris I. Shraiman | First 5 Authors: Farzan Vafa, Mark J. Bowick, M. Cristina Marchetti, Boris I. Shraiman, | Summary: Recent experiments and numerical studies have drawn attention to the dynamics of active nematics. Two-dimensional active nematics flow spontaneously and exhibit spatiotemporal chaotic flows with proliferation of topological defects in the nematic texture. […]

Kavli Affiliate: Bruce Macintosh | First 5 Authors: Ji Wang, Jason Wang, Bo Ma, Jeffrey Chilcote, Steve Ertel | Summary: Comparing chemical abundances of a planet and the host star reveals the origin and formation path. Stellar abundance is measured with high-resolution spectroscopy. Planet abundance, on the other hand, is usually inferred from low-resolution data. […]
Kavli Affiliate: Anthony Challinor | First 5 Authors: Antón Baleato Lizancos, Anthony Challinor, Julien Carron, , | Summary: Searches for the imprint of primordial gravitational waves in degree-scale CMB $B$-mode polarisation data must account for significant contamination from gravitational lensing. Fortunately, the lensing effects can be partially removed by combining high-resolution $E$-mode measurements with an […]
Kavli Affiliate: Ke Wang | First 5 Authors: Yizhen Wang, Mohannad Alhanahnah, Ke Wang, Mihai Christodorescu, Somesh Jha | Summary: Source code attribution approaches have achieved remarkable accuracy thanks to the rapid advances in deep learning. However, recent studies shed light on their vulnerability to adversarial attacks. In particular, they can be easily deceived by […]
Kavli Affiliate: Gregory D. Fuchs | First 5 Authors: Albert M. Park, Zhen Chen, Xiyue S. Zhang, Lijun Zhu, David A. Muller | Summary: Magnetic skyrmions hold promise for spintronic devices. To explore the dynamical properties of skyrmions in devices, a nanoscale method to image spin textures in response to a stimulus is essential. Here, […]
Kavli Affiliate: Li Xin Li | First 5 Authors: Bo Li, Xin Li, Wang Gao, Qing Jiang, | Summary: Surface energy is fundamental in controlling surface properties and surface-driven processes like heterogeneous catalysis, as adsorption energy is. It is thus crucial to establish an effective scheme to determine surface energy and its relation with adsorption […]
Kavli Affiliate: Toshiyuki Kobayashi | First 5 Authors: Toshiyuki Kobayashi, , , , | Summary: Geometric symmetry induces symmetries of function spaces, and the latter yields a clue to global analysis via representation theory. In this note we summarize recent developments on the general theory about how geometric conditions affect representation theoretic properties on function […]
