Kavli Affiliate: Jeevak Parpia | First 5 Authors: Dmytro Lotnyk, Anna Eyal, Nikolay Zhelev, Abhilash Sebastian, Yefan Tian | Summary: We examine the discontinuous first-order superfluid $^3$He A to B transition in the vicinity of the polycritical point (2.232 mK and 21.22 bar). We find path-dependent transitions: cooling at fixed pressure yields a well defined […]

Kavli Affiliate: Jia Liu | First 5 Authors: Xiaoyu Cao, Minghong Fang, Jia Liu, Neil Zhenqiang Gong, | Summary: Byzantine-robust federated learning aims to enable a service provider to learn an accurate global model when a bounded number of clients are malicious. The key idea of existing Byzantine-robust federated learning methods is that the service […]
Kavli Affiliate: Anna Frebel | First 5 Authors: Dmitrii Gudin, Derek Shank, Timothy C. Beers, Zhen Yuan, Guilherme Limberg | Summary: We derive dynamical parameters for a large sample of 446 $r$-process-enhanced (RPE) metal-poor stars in the halo and disk systems of the Milky Way, based on data releases from the $R$-Process Alliance, supplemented by […]
Kavli Affiliate: Cosmin Deaconu | First 5 Authors: Majd Ghrear, Sven E. Vahsen, Cosmin Deaconu, , | Summary: Directional detection of nuclear recoils is broadly desirable in nuclear and particle physics. At low recoil energies, this capability may be used to confirm the cosmological origin of a dark matter signal, to penetrate the so-called neutrino […]
Kavli Affiliate: Gregory J. Herczeg | First 5 Authors: Anupam Bhardwaj, Marina Rejkuba, Richard de Grijs, Soung-Chul Yang, Gregory J. Herczeg | Summary: We present new near-infrared, $JHK_s$, Period–Luminosity relations (PLRs) for RR Lyrae variables in the Messier 53 (M53 or NGC 5024) globular cluster. Multi-epoch $JHK_s$ observations, obtained with the WIRCam instrument on the […]
Kavli Affiliate: Ariel Amir | First 5 Authors: Jiseon Min, Ariel Amir, , , | Summary: Many unicellular organisms allocate their key proteins asymmetrically between the mother and daughter cells, especially in a stressed environment. A recent theoretical model is able to predict when the asymmetry in segregation of key proteins enhances the population fitness, […]
Kavli Affiliate: Anton R. Akhmerov | First 5 Authors: Helene Spring, Anton R. Akhmerov, Daniel Varjas, , | Summary: Protection of topological surface states by reflection symmetry breaks down when the boundary of the sample is misaligned with one of the high symmetry planes of the crystal. We demonstrate that this limitation is removed in […]
Kavli Affiliate: Kristin A. Persson | First 5 Authors: Rachel Woods-Robinson, Vladan Stevanović, Stephan Lany, Karen N. Heinselman, Kristin A. Persson | Summary: In materials science, it is often assumed that ground state crystal structures predicted by density functional theory are the easiest polymorphs to synthesize. Ternary nitride materials, with many possible metastable polymorphs, provide […]
