Bragg gravity-gradiometer using the ${}^1$S${}_0$-${}^3$P${}_1$ intercombination transition of ${}^{88}$Sr

Ruben P. del Aguila, Tommaso Mazzoni, Liang Hu +3

We present a gradiometer based on matter-wave interference of alkaline-earth-metal atoms, namely ${}^{88}$Sr. The coherent manipulation of the atomic external degrees of freedom is o…
