The Effects of the Local Environment on a Compact Radio Interferometer I: Cross-coupling in the Tianlai Dish Pathfinder Array

Posted by dbos Chicago

Kavli Affiliate: Albert Stebbins | First 5 Authors: Juhun Kwak, John Podczerwinski, Peter Timbie, Réza Ansari, John Marriner | Summary: The visibilities measured by radio astronomical interferometers include non-astronomical correlated signals that arise from the local environment of the array. These correlated signals are especially important in compact arrays such as those under development for […]

A two-site Kitaev chain in a two-dimensional electron gas

Posted by dbos Delft

Kavli Affiliate: Michael Wimmer | First 5 Authors: Sebastiaan L. D. ten Haaf, Qingzhen Wang, A. Mert Bozkurt, Chun-Xiao Liu, Ivan Kulesh | Summary: Artificial Kitaev chains can be used to engineer Majorana bound states (MBSs) in superconductor-semiconductor hybrids. In this work, we realize a two-site Kitaev chain in a two-dimensional electrongas by coupling two […]

Quantifying Interstellar Extinction at High Galactic Latitudes

Posted by klaurent Cambridge

Kavli Affiliate: Kaisey Mandel | Summary:A detailed map of the distribution of dust at high Galactic latitudes is essential for future cosmic microwave background (CMB) polarization experiments because the dust, while diffuse, remains a significant foreground in these regions. We develop a Bayesian model to identify a region of the Hertzsprung-Russell (HR) diagram suited to […]

Exploring Active Learning in Meta-Learning: Enhancing Context Set Labeling

Posted by dbos Peking

Kavli Affiliate: Jing Wang | First 5 Authors: Wonho Bae, Jing Wang, Danica J. Sutherland, , | Summary: Most meta-learning methods assume that the (very small) context set used to establish a new task at test time is passively provided. In some settings, however, it is feasible to actively select which points to label; the […]
