In-orbit operation of an atomic clock based on laser-cooled 87Rb atoms

Publikováno v: Nature Communications, Vol 9, Iss 1, Pp 1-8 (2018)

Cold atom clocks are among the most precise measuring devices and play key roles in everyday life and scientific explorations. Here the authors demonstrate the first in-orbit atomic clock using cold Rb atoms operating in microgravity and opening poss
