Kavli Affiliate: Stephanie Wehner | First 5 Authors: Scarlett Gauthier, Gayane Vardoyan, Stephanie Wehner, , | Summary: Entanglement between quantum network nodes is often produced using intermediary devices – such as heralding stations – as a resource. When scaling quantum networks to many nodes, requiring a dedicated intermediary device for every pair of nodes introduces […]
Kavli Affiliate: Joel E. Moore | First 5 Authors: Christopher W. Wächtler, Joel E. Moore, , , | Summary: The gapped symmetric phase of the Affleck-Kennedy-Lieb-Tasaki (AKLT) model exhibits fractionalized spins at the ends of an open chain. We show that breaking SU(2) symmetry and applying a global spin-lowering dissipator achieves synchronization of these fractionalized […]

Kavli Affiliate: Max Tegmark | First 5 Authors: Max Tegmark, Steve Omohundro, , , | Summary: We describe a path to humanity safely thriving with powerful Artificial General Intelligences (AGIs) by building them to provably satisfy human-specified requirements. We argue that this will soon be technically feasible using advanced AI for formal verification and mechanistic […]
Kavli Affiliate: Chiara Daraio | First 5 Authors: Tommaso Magrini, Chelsea Fox, Adeline Wihardja, Athena Kolli, Chiara Daraio | Summary: Composites with high strength and high fracture resistance are desirable for structural and protective applications. Most composites, however, suffer from poor damage tolerance and are prone to unpredictable fractures. Understanding the behavior of materials with […]
Kavli Affiliate: Herman L. Marshall | First 5 Authors: Ping Zhou, Dmitry Prokhorov, Riccardo Ferrazzoli, Yi-Jung Yang, Patrick Slane | Summary: Young supernova remnants (SNRs) strongly modify surrounding magnetic fields, which in turn play an essential role in accelerating cosmic rays (CRs). X-ray polarization measurements probe magnetic field morphology and turbulence at the immediate acceleration […]
Kavli Affiliate: Cori Bargmann | Authors: Elias Scheer and Cori Bargmann | Summary: Foraging animals optimize feeding decisions by adjusting both common and rare behavioral patterns. Here, we characterize the relationship between an animal’s arousal state and a rare decision to leave a patch of bacterial food. Using long-term tracking and behavioral state classification, we […]
Kavli Affiliate: Jia Liu | First 5 Authors: Shuailiang Ge, Jinhui Guo, Jia Liu, , | Summary: We present a novel mechanism for the primordial black hole (PBH) production within the QCD axion framework. We take the case where the Peccei-Quinn symmetry breaks during inflation, resulting in a $N_{rm DW}=1$ string-wall network that re-enters horizon […]
Kavli Affiliate: Marshall W. Bautz | First 5 Authors: Christian T. Norseth, Daniel R. Wik, John A. ZuHone, Eric D. Miller, Marshall W. Bautz | Summary: In the outskirts of galaxy clusters, entropy profiles measured from X-ray observations of the hot intracluster medium (ICM) drops off unexpectedly. One possible explanation for this effect is gas […]
