In ongoing collaboration with physicists from Novosibirsk, we demonstrated a scheme to reduce the instability of the blackbody-radiation (BBR) shift in optical clocks to below 10−19. To achieve this, one has to combine at least two clock transitions with different BBR shift sensitivities to form a...
