InSbAs two-dimensional electron gases as a platform for topological superconductivity

Kavli Affiliate: Giordano Scappucci | First 5 Authors: Christian M. Moehle, Chung Ting Ke, Qingzhen Wang, Candice Thomas, Di Xiao | Summary: Topological superconductivity can be engineered in semiconductors with strong spin-orbit interaction coupled to a superconductor. Experimental advances in this field have often been triggered by the development of new hybrid material systems. Among […]

An Efficient Training Approach for Very Large Scale Face Recognition

Kavli Affiliate: Zheng Zhu | First 5 Authors: Kai Wang, Shuo Wang, Panpan Zhang, Zhipeng Zhou, Zheng Zhu | Summary: Face recognition has achieved significant progress in deep learning era due to the ultra-large-scale and welllabeled datasets. However, training on the outsize datasets is time-consuming and takes up a lot of hardware resource. Therefore, designing […]

Optical Spectroscopy of Dual Quasar Candidates from the Subaru HSC-SSP program

Kavli Affiliate: John D. Silverman | First 5 Authors: Shenli Tang, John D. Silverman, Xuheng Ding, Junyao Li, Khee-Gan Lee | Summary: We report on a spectroscopic program to search for dual quasars using Subaru Hyper Suprime-Cam (HSC) images of SDSS quasars which represent an important stage during galaxy mergers. Using Subaru/FOCAS and Gemini-N/GMOS, we […]

An Empirical Background Model for the NICER X-ray Timing Instrument

Kavli Affiliate: Gregory Y. Prigozhin | First 5 Authors: [#item_custom_name[1]], [#item_custom_name[2]], [#item_custom_name[3]], [#item_custom_name[4]], [#item_custom_name[5]] | Summary: NICER has a comparatively low background rate, but it is highly variable, and its spectrum must be predicted using measurements unaffected by the science target. We describe an empirical, three-parameter model based on observations of seven pointing directions that […]

External Calibrator in Global Signal Experiment for Detection of the Epoch of Reionization

Kavli Affiliate: Kejia Lee | First 5 Authors: [#item_custom_name[1]], [#item_custom_name[2]], [#item_custom_name[3]], [#item_custom_name[4]], [#item_custom_name[5]] | Summary: We present a conceptual design study of external calibrators in the 21 cm experiment towards detecting the globally averaged radiation of the epoch of reionization (EoR). Employment of external calibrator instead of internal calibrator commonly used in current EoR experiments […]

Constraints on black-hole charges with the 2017 EHT observations of M87*

Kavli Affiliate: Bradford A. Benson | First 5 Authors: Prashant Kocherlakota, Luciano Rezzolla, Heino Falcke, Christian M. Fromm, Michael Kramer | Summary: Our understanding of strong gravity near supermassive compact objects has recently improved thanks to the measurements made by the Event Horizon Telescope (EHT). We use here the M87* shadow size to infer constraints […]
