Kavli Affiliate: Daniel C. Ralph | First 5 Authors: Xiaoxi Huang, Xiaoxi Huang, , , | Summary: To achieve efficient anti-damping switching of nanoscale magnetic memories with perpendicular magnetic anisotropy using spin-orbit torque requires that the anti-damping spin-orbit torque have a strong out-of-plane component. The spin anomalous Hall effect and the planar Hall effect spin […]
Kavli Affiliate: Seth Blackshaw | Authors: Kurt Weir, Pin Lyu, Sangeetha Kandoi, Roujin An, Nicole Pannullo, Isabella Palazzo, Jared Tangeman, Jun Shi, Steven DeVries, Dana Merriman, Jiang Qian and Seth Blackshaw | Summary: Evolutionary adaptation to diurnal vision in ground squirrels has led to the development of a cone-dominant retina, in stark contrast to the […]
Kavli Affiliate: Ting Xu | First 5 Authors: Yuting Wu, Yuting Wu, , , | Summary: A development effort to improve the performance of superconducting radio-frequency half-wave resonators (SRF HWRs) is underway at the Facility for Rare Isotope Beams (FRIB), where 220 such resonators are in operation. Our goal was to achieve an intrinsic quality […]
Kavli Affiliate: Felix Fischer | First 5 Authors: Javier Cembrano, Javier Cembrano, , , | Summary: We study the selection of agents based on mutual nominations, a theoretical problem with many applications from committee selection to AI alignment. As agents both select and are selected, they may be incentivized to misrepresent their true opinion about […]
Kavli Affiliate: Claudio Ricci | First 5 Authors: Federico Esposito, Federico Esposito, , , | Summary: The distribution of molecular gas on small scales regulates star formation and the growth of supermassive black holes in galaxy centers, yet the role of active galactic nuclei (AGN) feedback in shaping this distribution remains poorly constrained. We investigate […]
Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Meredith Neyer, Meredith Neyer, , , | Summary: We use the THESAN radiation-hydrodynamics simulations to investigate how Lyman-$alpha$ emitters (LAEs) trace ionized bubble sizes during the Epoch of Reionization. We generate realistic LAE catalogs by combining accurate intrinsic Ly$alpha$ production and intergalactic transmission with an empirical model […]
Kavli Affiliate: Hitoshi Murayama | First 5 Authors: Joshua N. Benabou, Joshua N. Benabou, , , | Summary: The absence of a neutron electric dipole moment (EDM) constrains the quantum chromodynamics (QCD) theta angle to be less than one part in ten billion, posing the Strong $CP$ problem. We revisit two classes of proposed solutions. […]
Kavli Affiliate: Alireza Marandi | First 5 Authors: Selina Zhou, Selina Zhou, , , | Summary: Supercontinuum light sources are widely used for applications ranging from imaging to sensing and frequency comb stabilization. The most common mechanisms for their generation rely on cubic nonlinearities, for instance in crystals, optical fibers, and integrated photonics. However, quadratic […]
Kavli Affiliate: John Serences | Authors: Holly Kular and John Serences | Summary: Visual working memory (WM) enables the maintenance of information that is no longer present in the environment. Some accounts propose that WM is supported by abstract representations so that new sensory inputs do not interfere with existing memories. Others posit that early […]
Kavli Affiliate: Jing Wang | First 5 Authors: Sijia Li, Sijia Li, , , | Summary: The interstellar medium (ISM) in high-redshift galaxies exhibits significantly higher electron densities ($n_rm e$) than in the local universe. To investigate the origin of this trend, we analyze a sample of 9590 centrally star-forming galaxies with stellar masses greater […]
