Kavli Affiliate: Grace Xing | First 5 Authors: Joseph Casamento, Hyunjea Lee, Takuya Maeda, Ved Gund, Kazuki Nomoto | Summary: Epitaxial Sc$_x$Al$_{1-x}$N thin films of ~100 nm thickness grown on metal polar GaN exhibit significantly enhanced relative dielectric permittivity ($epsilon_r$) values relative to AlN. $epsilon_r$ values of ~17 to 21 for Sc contents of 17 […]
Kavli Affiliate: Carlos E. M. Wagner | First 5 Authors: Jia Liu, Navin McGinnis, Carlos E. M. Wagner, Xiao-Ping Wang, | Summary: We investigate a concrete scenario of a light scalar with a mass around 1 MeV which can be connected to the origin of neutrino masses and simultaneously survive current bounds on relativistic degrees […]
Kavli Affiliate: Alexander P. Ji | First 5 Authors: Rohan P. Naidu, Alexander P. Ji, Charlie Conroy, Ana Bonaca, Yuan-Sen Ting | Summary: The astrophysical origins of $r$-process elements remain elusive. Neutron star mergers (NSMs) and special classes of core-collapse supernovae (rCCSNe) are leading candidates. Due to these channels’ distinct characteristic timescales (rCCSNe: prompt, NSMs: […]
Kavli Affiliate: Yawen Sun | First 5 Authors: Qing Wu, Yuwei Li, Yawen Sun, Yan Zhou, Hongjiang Wei | Summary: High Resolution (HR) medical images provide rich anatomical structure details to facilitate early and accurate diagnosis. In MRI, restricted by hardware capacity, scan time, and patient cooperation ability, isotropic 3D HR image acquisition typically requests […]
Kavli Affiliate: Andrew Vanderburg | First 5 Authors: Siyi Xu, Hannah Diamond-Lowe, Ryan J. MacDonald, Andrew Vanderburg, Simon Blouin | Summary: WD 1856+534 b is a Jupiter-sized, cool giant planet candidate transiting the white dwarf WD 1856+534. Here, we report an optical transmission spectrum of WD 1856+534 b obtained from ten transits using the Gemini […]
