Kavli Affiliate: Katja C. Nowack | First 5 Authors: Brian T. Schaefer, Katja C. Nowack, , , | Summary: The valleys in hexagonal two-dimensional systems with broken inversion symmetry carry an intrinsic orbital magnetic moment. Despite this, such systems possess zero net magnetization unless additional symmetries are broken, since the contributions from both valleys cancel. […]

Kavli Affiliate: Harry A. Atwater | First 5 Authors: Joeson Wong, Stefan T. Omelchenko, Harry A. Atwater, , | Summary: The theoretical maximum efficiency of a solar cell is typically characterized by a detailed balance of optical absorption and emission for a semiconductor in the limit of unity radiative efficiency and an ideal step-function response […]
Kavli Affiliate: Harry A. Atwater | First 5 Authors: Joeson Wong, Artur R. Davoyan, Bolin Liao, Andrey Krayev, Kiyoung Jo | Summary: Van der Waals materials exhibit naturally passivated surfaces and can form versatile heterostructures, enabling observation of carrier transport mechanisms not seen in three-dimensional materials. Here we report observation of a "band bending junction", […]
Kavli Affiliate: Toshiya Namikawa | First 5 Authors: Maya Mallaby-Kay, Zachary Atkins, Simone Aiola, Stefania Amodeo, Jason E. Austermann | Summary: Two recent large data releases for the Atacama Cosmology Telescope (ACT), called DR4 and DR5, are available for public access. These data include temperature and polarization maps that cover nearly half the sky at […]
Kavli Affiliate: Kristin A. Persson | First 5 Authors: Casper W. Andersen, Rickard Armiento, Evgeny Blokhin, Gareth J. Conduit, Shyam Dwaraknath | Summary: The Open Databases Integration for Materials Design (OPTIMADE) consortium has designed a universal application programming interface (API) to make materials databases accessible and interoperable. We outline the first stable release of the […]
Kavli Affiliate: Bruce Macintosh | First 5 Authors: N. Jeremy Kasdin, Vanessa P. Bailey, Bertrand Mennesson, Robert T. Zellem, Marie Ygouf | Summary: The Coronagraph Instrument (CGI) on the Nancy Grace Roman Space Telescope will demonstrate the high-contrast technology necessary for visible-light exoplanet imaging and spectroscopy from space via direct imaging of Jupiter-size planets and […]
Kavli Affiliate: Anna Frebel | First 5 Authors: Yuta Tarumi, Naoki Yoshida, Anna Frebel, , | Summary: Ultra-faint dwarf galaxies (UFDs) are promising observable proxies to building blocks of galaxies formed in the early Universe. We study the formation and evolution of UFDs using cosmological hydrodynamic simulations. In particular, we show that a major merger […]
Kavli Affiliate: Naoshi Sugiyama | First 5 Authors: Mutsumi Minoguchi, Atsushi J. Nishizawa, Tsutomu T. Takeuchi, Naoshi Sugiyama, | Summary: The void ellipticity distribution today can be well explained by the tidal field. Going a step further from the overall distribution, we investigate individuality on the tidal response of void shape in non-linear dynamical evolution. […]
Kavli Affiliate: Eliska Greplova | First 5 Authors: Agnes Valenti, Guliuxin Jin, Julian Léonard, Sebastian D. Huber, Eliska Greplova | Summary: Large-scale quantum devices provide insights beyond the reach of classical simulations. However, for a reliable and verifiable quantum simulation, the building blocks of the quantum device require exquisite benchmarking. This benchmarking of large scale […]
