Observing Spin-Squeezed States under Spin-Exchange Collisions for a Second
Using the platform of a trapped-atom clock on a chip, we observe the time evolution of spin-squeezed hyperfine clock states in ultracold rubidium atoms on previously inaccessible time scales up to 1 s. The spin degree of freedom remains squeezed after 0.6 s, which is consistent with the limit impose...
