Sympathetic cooling of molecular ion motion to the ground state

Rene Rugango, James E. Goeders, Thomas H. Dixon +5

We demonstrate sympathetic sideband cooling of a ${}^{40}$CaH${}^{+}$ molecular ion co-trapped with a ${}^{40}$Ca${}^{+}$ atomic ion in a linear Paul trap. Both axial modes of the two-ion…
