Kavli Affiliate: Zhuo Li | First 5 Authors: Shaoshan Wang, Pengcheng Ding, Zhuo Li, Cristina Mattioli, Wenlong E | Summary: Transition metal carbides have sparked unprecedented enthusiasm as high-performance catalysts in recent years. Still, the catalytic properties of copper (Cu) carbide remain unexplored. By introducing subsurface carbon (C) to Cu(111), displacement reaction of proton in […]
Kavli Affiliate: Zhuo Li | First 5 Authors: Shaoshan Wang, Zhuo Li, Pengcheng Ding, Cristina Mattioli, Wujun Huang | Summary: On-surface synthesis (OSS) involving relatively high energy barriers remains challenging due to a typical dilemma: firm molecular anchor is required to prevent molecular desorption upon the reaction, whereas sufficient lateral mobility is crucial for subsequent […]
Kavli Affiliate: Paul W. K. Rothemund | First 5 Authors: Tyler D. Ross, Dino Osmanović, John F. Brady, Paul W. K. Rothemund, | Summary: Control of self-propelled particles is central to the development of many microrobotic technologies, from dynamically reconfigurable materials to advanced lab-on-a-chip systems. However, there are few physical principles by which particle trajectories […]
Kavli Affiliate: Paul W. K. Rothemund | First 5 Authors: Tyler D. Ross, Dino Osmanović, John F. Brady, Paul W. K. Rothemund, | Summary: Snell’s law, which encompasses both refraction and total internal reflection, provides the foundation for ray optics and all lens-based instruments, from microscopes to telescopes. Refraction results when light crosses the interface […]
Kavli Affiliate: Nickolay Y. Gnedin | First 5 Authors: Huanqing Chen, Nickolay Y. Gnedin, Philip Mansfield, , | Summary: Using a suite of self-similar cosmological simulations, we measure the probability distribution functions (PDFs) of real-space density, redshift-space density, and their geometric mean. We find that the real-space density PDF is well-described by a function of […]
Kavli Affiliate: Nicola Omodei | First 5 Authors: Milena Crnogorčević, Regina Caputo, Manuel Meyer, Nicola Omodei, Michael Gustafsson | Summary: Light axion-like particles (ALPs) are expected to be abundantly produced in core-collapse supernovae (CCSNe), resulting in a $sim$10-second long burst of ALPs. These particles subsequently undergo conversion into gamma-rays in external magnetic fields to produce […]
Kavli Affiliate: Michael Keiser | Authors: Laura M Gunsalus, Michael J. Keiser and Katherine S Pollard | Summary: ABSTRACT Predictive remapping — the ability of cells in retinotopic brain areas to transiently exhibit spatio-temporal retinotopic shifts beyond the spatial extent of their classical receptive fields — has been proposed as a primary mechanism that stabilizes […]
Kavli Affiliate: Toeno Van Der Sar | First 5 Authors: Joris J. Carmiggelt, Olaf C. Dreijer, Carsten Dubs, Oleksii Surzhenko, Toeno van der Sar | Summary: Yttrium iron garnet (YIG) is a magnetic insulator with record-low damping, allowing spin-wave transport over macroscopic distances. Doping YIG with gallium ions greatly reduces the demagnetizing field and introduces […]
Kavli Affiliate: Kiyoshi Masui | First 5 Authors: Savannah Cary, Juan Mena-Parra, Calvin Leung, Kiyoshi Masui, J. F. Kaczmarek | Summary: As the Canadian Hydrogen Intensity Mapping Experiment (CHIME) has become the leading instrument for detecting Fast Radio Bursts (FRBs), CHIME/FRB Outriggers will use very-long-baseline interferometry (VLBI) to localize FRBs with milliarcsecond precision. The CHIME […]
Kavli Affiliate: Luis C. Ho | First 5 Authors: Vivek Kumar Jha, Ravi Joshi, Hum Chand, Xue-Bing Wu, Luis C. Ho | Summary: We present the accretion disk size estimates for a sample of 19 active galactic nuclei (AGN) using the optical $g$, $r$, and $i$ band light curves obtained from the Zwicky Transient Facility […]
