1. Correlation between Atomic Size Ratio and Poisson's Ratio in Metallic Glasses

Abstract

We report the correlation between atomic size ratio and Poisson's ratio in various metallic glasses. It is found that atomic size ratio has an influence on the atomic packing density of metallic glasses, which would significantly impact the shear modulus rather than bulk modulus. The findings may be helpful for understanding the structural origin of Poisson's ratio in metallic glasses, and are instructive for designing tough metallic glasses with large Poisson's ratio.

2. Cooling and Crystallization of Trapped 113 Cd + Ions for Atomic Clock

Author

Subjects

Abstract

We report recent experimental progress toward a trapped 113Cd+ ion microwave frequency standard. With laser cooling, a large number of trapped cadmium ions are cooled to crystallization and the temperature of the ion crystal is measured to be 16±3 mK. The second order Doppler frequency shift, a main limiting factor of the atomic clock's performance, is estimated to be less than 1 × 10−16.
