Kavli Affiliate: Darrell G. Schlom | First 5 Authors: Zubia Hasan, Zubia Hasan, , , | Summary: Geometrically frustrated lattices can display a range of correlated phenomena, ranging from spin frustration and charge order to dispersionless flat bands due to quantum interference. One particularly compelling family of such materials is the half-valence spinel Li$B_2$O$_4$ materials. […]

Kavli Affiliate: John D. Silverman | First 5 Authors: Zhaoxuan Liu, John D. Silverman, Emanuele Daddi, Boris S. Kalita, Annagrazia Puglisi | Summary: We present high-resolution and spatially-matched observations with JWST and ALMA of a starburst galaxy (PACS-830) at $z=1.46$. The NIRCam observations mainly trace the stellar light while the CO ($J$=5–4) observations map the […]
Kavli Affiliate: Robert A. Simcoe | First 5 Authors: Viraj Karambelkar, Mansi Kasliwal, Kishalay De, Danielle Frostig, Robert Stein | Summary: We present WNTR23bzdiq/WTP19aalzlk, a slow eruption of an early-asymptotic giant branch (AGB) star in M31 identified by the Wide-field Infrared Transient Explorer (WINTER) near-infrared and the NEOWISE mid-infrared surveyors. This source brightened gradually over […]
Kavli Affiliate: Misao Sasaki | First 5 Authors: Xinpeng Wang, Misao Sasaki, Ying-li Zhang, , | Summary: We report a novel mechanism where two families of primordial black holes (PBHs) may form at nearly the same comoving scales but at two different epochs. It is realized in two-stage inflation where a non-inflationary stage is sandwiched […]
Kavli Affiliate: Wei Gao | First 5 Authors: Fan Xu, Fan Xu, , , | Summary: Decision trees and forests have achieved successes in various real applications, most working with all testing classes known in training data. In this work, we focus on learning with augmented class via forests, where an augmented class may appear […]

Kavli Affiliate: Long Zhang | First 5 Authors: Yuejiu Zhao, Long Zhang, Fu-Chun Zhang, , | Summary: Quantum anomalous Hall (QAH) systems with high Chern number ($|C|>1$) are rare. This Letter introduces a Haldane-graphene multilayer heterostructure hosting QAH states with arbitrary Chern number. In a rhombohedral-stacked graphene $N$-layer, the Dirac points at $K_{pm}$ become $N^text{th}$-order […]
Kavli Affiliate: Masahiro Takada | First 5 Authors: Ryo Terasawa, Masahiro Takada, Toshiki Kurita, Sunao Sugiyama, | Summary: The $S_8$ value inferred from the Subaru Hyper Suprime-Cam (HSC) Year 3 cosmic shear data, under the assumption of the flat $Lambda$CDM model, is 2-3$sigma$ lower than that inferred from observations of the early-time universe, such as […]
