Sympathetic Cooling of Molecular Ion Motion to the Ground State
Abstract
We demonstrate sympathetic sideband cooling of a 40CaH+ molecular ion co-trapped with a 40Ca+ atomic ion in a linear Paul trap. Both axial modes of the two-ion chain are simultaneously cooled to near the ground state of motion. The center of mass mode is cooled to an average quanta of harmonic motion nCOM = 0.13 + or - 0.03, corresponding to a temperature of 12.47 + or - 0.03 K. The breathing mode is cooled to nBM = 0.05 + or - 0.02, corresponding to a temperature of 15.36 + or - 0.01 K.
