[作者:Loth, S; Etzkorn, M; Lutz, CP; Eigler, DM; Heinrich, AJ,期刊:Science, 页码:1628-1630 , 文章类型: Article,,卷期:2010年329-5999]
- Single spins in solid-state systems are often considered prime candidates for the storage of quantum information, and their interaction with the environment the main limiting factor for the realization of such schemes. T...
- The Ubiquity of Micrometer-Sized Dust Grains in the Dense Interstellar Medium
[作者:Pagani, L; Steinacker, J; Bacmann, A; Stutz, A; Henning, T,期刊:Science, 页码:1622-1624 , 文章类型: Article,,卷期:2010年329-5999]
- Cold molecular clouds are the birthplaces of stars and planets, where dense cores of gas collapse to form protostars. The dust mixed in these clouds is thought to be made of grains of an average size of 0.1 micrometer. W...
- Optical Clocks and Relativity
[作者:Chou, CW; Hume, DB; Rosenband, T; Wineland, DJ,期刊:Science, 页码:1630-1633 , 文章类型: Article,,卷期:2010年329-5999]
- Observers in relative motion or at different gravitational potentials measure disparate clock rates. These predictions of relativity have previously been observed with atomic clocks at high velocities and with large chan...
- Alkali-Stabilized Pt-OHx Species Catalyze Low-Temperature Water-Gas Shift Reactions
