Spherical adjunctions of stable $infty$-categories and the relative S-construction

Kavli Affiliate: Mikhail Kapranov | Summary:We develop the theory of semi-orthogonal decompositions and spherical functors in the framework of stable $infty$-categories. Building on this, we study the relative Waldhausen S-construction $S_bullet(F)$ of a spherical functor $F$ and equip it with a natural paracyclic structure (“rotational symmetry”). This fulfills a part of the general program to […]

A Hint of a Low-Energy Excess in Cosmic-Ray Fluorine

Kavli Affiliate: Troy Porter | Summary:Since its launch, the Alpha Magnetic Spectrometer-02 (AMS-02) has delivered outstanding quality measurements of the spectra of cosmic-ray (CR) species, $barp$, $e^pm$, and nuclei (H–O, Ne, Mg, Si, Fe), which resulted in a number of breakthroughs. The most recent AMS-02 result is the measurement of the spectrum of CR fluorine […]

Inferring Black Hole Properties from Astronomical Multivariate Time Series with Bayesian Attentive Neural Processes

Kavli Affiliate: Philip J. Marshall | First 5 Authors: Ji Won Park, Ashley Villar, Yin Li, Yan-Fei Jiang, Shirley Ho | Summary: Among the most extreme objects in the Universe, active galactic nuclei (AGN) are luminous centers of galaxies where a black hole feeds on surrounding matter. The variability patterns of the light emitted by […]

Highly tunable magnetic phases in transition metal dichalcogenide Fe$_{1/3+δ}$NbS$_2$

Kavli Affiliate: Jeffrey B. Neaton | First 5 Authors: Shan Wu, Zhijun Xu, Shannon C. Haley, Sophie F. Weber, Arany Acharya | Summary: Layered transition metal dichalcogenides (TMDCs) host a plethora of interesting physical phenomena ranging from charge order to superconductivity. By introducing magnetic ions into 2H-NbS$_2$, the material forms a family of magnetic intercalated […]

Enhanced spin-orbit coupling and orbital moment in ferromagnets by electron correlations

Kavli Affiliate: Bo Gu | First 5 Authors: Ze Liu, Jing-Yang You, Bo Gu, Sadamichi Maekawa, Gang Su | Summary: In atomic physics, the Hund rule says that the largest spin and orbital state is realized due to the interplay of the spin-orbit coupling (SOC) and the Coulomb interactions. Here, we show that in ferromagnetic […]
