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 […]
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 […]
Kavli Affiliate: Masahito Yamazaki | First 5 Authors: Dmitry Galakhov, Wei Li, Masahito Yamazaki, , | Summary: We introduce a class of new algebras, the shifted quiver Yangians, as the BPS algebras for type IIA string theory on general toric Calabi-Yau three-folds. We construct representations of the shifted quiver Yangian from general subcrystals of the […]
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 […]
