A primordial atmospheric origin of hydrospheric deuterium enrichment on Mars

Kavli Affiliate: Laura Schaefer | First 5 Authors: Kaveh Pahlevan, Laura Schaefer, Linda T. Elkins-Tanton, Steven J. Desch, Peter R. Buseck | Summary: The deuterium-to-hydrogen (D/H or 2H/1H) ratio of Martian atmospheric water (~6x standard mean ocean water, SMOW) is higher than that of known sources, requiring planetary enrichment. A recent measurement by NASA’s Mars […]

Platform-agnostic waveguide integration of high-speed photodetectors with evaporated tellurium thin films

Kavli Affiliate: Ali Javey | First 5 Authors: Geun Ho Ahn, Alexander D. White, Hyungjin Kim, Naoki Higashitarumizu, Felix M. Mayor | Summary: Many attractive photonics platforms still lack integrated photodetectors due to inherent material incompatibilities and lack of process scalability, preventing their widespread deployment. Here we address the problem of scalably integrating photodetectors in […]

Quantum precision limits of displacement noise free interferometers

Kavli Affiliate: Rana X. Adhikari | First 5 Authors: Tuvia Gefen, Rajashik Tarafder, Rana X. Adhikari, Yanbei Chen, | Summary: Current laser-interferometric gravitational wave detectors suffer from a fundamental limit to their precision due to the displacement noise of optical elements contributed by various sources. Several schemes for Displacement-Noise Free Interferometers (DFI) have been proposed […]
