VisRec: A Semi-Supervised Approach to Radio Interferometric Data Reconstruction

Kavli Affiliate: Feng Wang | First 5 Authors: Ruoqi Wang, Haitao Wang, Qiong Luo, Feng Wang, Hejun Wu | Summary: Radio telescopes produce visibility data about celestial objects, but these data are sparse and noisy. As a result, images created on raw visibility data are of low quality. Recent studies have used deep learning models […]

Controllable suppression of the unconventional superconductivity in bulk and thin-film Sr$_{2}$RuO$_{4}$ via high-energy electron irradiation

Kavli Affiliate: Darrell G. Schlom | First 5 Authors: Jacob P. Ruf, Hilary M. L. Noad, Romain Grasset, Ludi Miao, Elina Zhakina | Summary: In bulk Sr$_{2}$RuO$_{4}$, the strong sensitivity of the superconducting transition temperature $T_{text{c}}$ to nonmagnetic impurities provides robust evidence for a superconducting order parameter that changes sign around the Fermi surface. In […]
