Ground state sideband ion sub-Hertz heating rate Atomic Physics
2012/5/29
We demonstrate resolved sideband laser cooling of a single 40Ca+ ion in a macroscopic linear radio frequency trap with a radial diagonal electrode spacing of 7 mm and an rf drive frequency of just 3.7...
Mid-Holocene sea-surface temperature reconstruction using fossil corals from Kume Island, Ryukyu, Japan
Holocene SST coral Sr/Ca East China Seatal proxy
2017/4/11
The relative warmth and stability of the Holocene was punctuated by several brief cold events. Whereas these cold
events on a global scale are widely reported, the lack of records from regions such a...
