blackbody radiation shift assessment for a lutetium ion clock
Nature Communications, 2018Co-Authors: K J Arnold, R Kaewuam, M D BarrettAbstract:The accuracy of state-of-the-art Atomic clocks is derived from the insensitivity of narrow optical Atomic resonances to environmental perturbations. Two such resonances in singly ionized lutetium have been identified with potentially lower sensitivities compared to other clock candidates. Here we report measurement of the most significant unknown Atomic Property of both transitions, the static differential scalar polarizability. From this, the fractional blackbody radiation shift for one of the transitions is found to be −1.36(9) × 10−18 at 300 K, the lowest of any established optical Atomic clock. In consideration of leading systematic effects common to all ion clocks, both transitions compare favorably to the most accurate ion-based clocks reported to date. This work firmly establishes Lu+ as a promising candidate for a future generation of more accurate optical Atomic clocks. There is a continuous effort to improve the accuracy of Atomic clocks. Here the authors measure the static differential scalar polarizability of Lutetium ion resonant transitions and its lower light shift from blackbody radiation makes it a promising candidate for ion-based Atomic clocks.

a general representation scheme for crystalline solids based on voronoi tessellation real feature values and Atomic Property data
Science and Technology of Advanced Materials, 2018Co-Authors: Randy Jalem, Masanobu Nakayama, Yusuke Noda, Ichiro Takeuchi, Yoshitaka Tateyama, Hisatsugu YamazakiAbstract:AbstractIncreasing attention has been paid to materials informatics approaches that promise efficient and fast discovery and optimization of functional inorganic materials. Technical breakthrough is urgently requested to advance this field and efforts have been made in the development of materials descriptors to encode or represent characteristics of crystalline solids, such as chemical composition, crystal structure, electronic structure, etc. We propose a general representation scheme for crystalline solids that lifts restrictions on atom ordering, cell periodicity, and system cell size based on structural descriptors of directly binned Voronoi-tessellation real feature values and Atomic/chemical descriptors based on the electronegativity of elements in the crystal. Comparison was made vs. radial distribution function (RDF) feature vector, in terms of predictive accuracy on density functional theory (DFT) material properties: cohesive energy (CE), density (d), electronic band gap (BG), and decomposition...
