## Description

 Title: Sympathetic Sideband Cooling Of Cah+ Author(s): Rugango, Rene Contributor(s): Brown, Kenneth R. Subject(s): Cold/Ultra-cold/Physics Abstract: We demonstrate sympathetic Doppler cooling and our progress towards sideband cooling of a CaH$^{+}$ ion co-trapped with a Ca$^{+}$ atomic ion in a linear Paul trap. Molecular ions are generally difficult to laser cool due to a lack of closed electronic transitions as a result of vibrational and rotational states. Despite this challenge, they can be cooled indirectly through their Coulombic interaction with a fluorescent atomic ion that is being directly laser cooled. Ions are firstly Doppler cooled to get to the Lamb-Dicke regime, where the ion motion is small relative to the excitation wavelength and then sideband cooled reaching temperatures below 1 $\mu$K. All the ions' axial modes (center of mass and breathing mode) and radial modes ( two center of mass and two tilt modes) are addressed, and the temperature is determined by examining the ratio of sidebands.
