Kavli Affiliate: Gregory D. Fuchs | First 5 Authors: Albert M. Park, Zhen Chen, Xiyue S. Zhang, Lijun Zhu, David A. Muller | Summary: Magnetic skyrmions hold promise for spintronic devices. To explore the dynamical properties of skyrmions in devices, a nanoscale method to image spin textures in response to a stimulus is essential. Here, […]
Kavli Affiliate: Li Xin Li | First 5 Authors: Bo Li, Xin Li, Wang Gao, Qing Jiang, | Summary: Surface energy is fundamental in controlling surface properties and surface-driven processes like heterogeneous catalysis, as adsorption energy is. It is thus crucial to establish an effective scheme to determine surface energy and its relation with adsorption […]
Kavli Affiliate: Toshiyuki Kobayashi | First 5 Authors: Toshiyuki Kobayashi, , , , | Summary: Geometric symmetry induces symmetries of function spaces, and the latter yields a clue to global analysis via representation theory. In this note we summarize recent developments on the general theory about how geometric conditions affect representation theoretic properties on function […]
Kavli Affiliate: Toshiyuki Kobayashi | First 5 Authors: Toshiyuki Kobayashi, Birgit Speh, , , | Summary: We consider branching laws for the restriction of some irreducible unitary representations $Pi$ of $G=O(p,q)$ to its subgroup $H=O(p-1,q)$. In Kobayashi (arXiv:1907.07994), the irreducible subrepresentations of $O(p-1,q)$ in the restriction of the unitary $Pi|_{O(p-1,q) }$ are determined. By considering […]
Kavli Affiliate: Paul L. Schechter | First 5 Authors: Anton T. Jaelani, Cristian E. Rusu, Issha Kayo, Anupreeta More, Alessandro Sonnenfeld | Summary: We present spectroscopic confirmation of three new two-image gravitationally lensed quasars, compiled from existing strong lens and X-ray catalogs. Images of HSC J091843.27$-$022007.5 show a red galaxy with two blue point sources […]
Kavli Affiliate: Yukinobu Toda | First 5 Authors: Yukinobu Toda, , , , | Summary: In this paper, we prove a window theorem for categorical Donaldson-Thomas theories on local surfaces as an analogue of window theorem for GIT quotient stacks. We give two applications of our main result. The first one is a proof of […]
