Kavli Affiliate: Kejia Lee | First 5 Authors: Zhengli Wang, Zhengli Wang, , , | Summary: In this work, we observe the nearby pulsar, PSR B1929$+$10, using the Five-hundred-meter Aperture Spherical radio Telescope (FAST). We find, for the first time, two new emission components with an extremely weak observed flux density of about $10^-4$ of […]
Kavli Affiliate: Rudolf Podgornik | First 5 Authors: Vijay Yadav, Vijay Yadav, , , | Summary: The ability to precisely control surface charge using charged polymers is fundamental to many nanotechnology applications, enabling the design and fabrication of materials with tailored properties and functionalities. Here, we study the effect of charge regulation (CR) on the […]
Kavli Affiliate: Long Zhang | First 5 Authors: Lei Chen, Lei Chen, , , | Summary: A common wisdom about quantum many-body systems is that emergent phases typically fall into either the Landau-Ginzburg paradigm or topological classifications. Experimentally realizing the intertwined emergence of spontaneous symmetry breaking and topological order remains challenging. Here, we present an […]
Kavli Affiliate: Masahiro Kawasaki | First 5 Authors: Hiroto Yanagisawa, Hiroto Yanagisawa, , , | Summary: We present a new constraint on the primordial helium abundance, $Y_mathrmP$, based on Subaru observations. A major source of uncertainty in previous $Y_mathrmP$ determinations is the lack of extremely metal-poor galaxies (EMPGs; $0.01-0.1Z_odot$), which have metallicities a few to […]
Kavli Affiliate: Toshiya Namikawa | First 5 Authors: Toshiya Namikawa, Toshiya Namikawa, , , | Summary: The recent measurement of baryonic acoustic oscillations (BAO) by the Dark Energy Spectroscopic Instrument (DESI) reveals a mild tension with observations of the cosmic microwave background (CMB) within the standard $Lambda$CDM cosmological model. This discrepancy leads to a preference […]
Kavli Affiliate: Shunsaku Horiuchi | First 5 Authors: Cecilia Lunardini, Cecilia Lunardini, , , | Summary: We present a new, state-of-the-art computation of the Diffuse Supernova Neutrino Background (DSNB), where we use neutrino spectra from multi-dimensional, multi-second core collapse supernova simulations – including both neutron-star and black-hole forming collapses – and binary evolution effects from […]
Kavli Affiliate: David A. Muller | First 5 Authors: Shannon S. Fender, Shannon S. Fender, , , | Summary: The interplay between symmetry and topology in magnetic materials makes it possible to engineer exotic phases and technologically useful properties. A key requirement for these pursuits is achieving control over local crystallographic and magnetic structure, usually […]
Kavli Affiliate: Bruce Macintosh | First 5 Authors: Anne E. Peck, Anne E. Peck, , , | Summary: Directly imaged substellar companions with well-constrained ages and masses serve as vital empirical benchmarks for planet formation and evolution models. Potential benchmark companions can be identified from astrometric accelerations of their host stars. We use Gaia DR3 […]
Kavli Affiliate: Feng Wang | First 5 Authors: Ruixiang Song, Ruixiang Song, , , | Summary: Metalenses, owing to their ultra-thin planar structures, present a promising solution for reducing endoscopic invasiveness. However, achieving high-quality imaging with minimal invasiveness (short focal length of metalens) remains a critical challenge. This paper presents a deep learning assisted metalens […]
Kavli Affiliate: Ting Xu | First 5 Authors: Zhiyi Chen, Zhiyi Chen, , , | Summary: Procrastination represents one of the most prevalent behavioral problems affecting individual health and societal productivity. Although it is often conceptualized as a form of self-control failure, its underlying neurocognitive mechanisms are poorly understood. A leading model posits that procrastination […]
