Combined atomic clock with blackbody-radiation-shift-induced instability below 10−19 under natural environment conditions

New Journal of Physics, 2021
We develop a method of synthetic frequency generation to construct an atomic clock with blackbody radiation (BBR) shift uncertainties below 10 ^−19 at environmental conditions with a very low level of temperature control.
