Preparation of a Heteronuclear Two-atom System in the 3D Motional Ground State in an Optical Tweezer

Kunpeng Wang, Xiaodong He, Ruijun Guo +7

We report the realization of a heteronuclear two-atom of ${}^{87}$Rb-${}^{85}$Rb in the ground state of an optical tweezer (OT). Starting by trapping two different isotopic single atom…
