    "abstract": "We study laser cooling of two ions that are trapped in a harmonic potential\nand interact by Coulomb repulsion. Sideband cooling in the Lamb-Dicke regime is\nshown to work analogously to sideband cooling of a single ion. Outside the\nLamb-Dicke regime, the incommensurable frequencies of the two vibrational modes\nresult in a quasi-continuous energy spectrum that significantly alters the\ncooling dynamics. The cooling time decreases nonlinearly with the linewidth of\nthe cooling transition, and the effect of trapping states which may slow down\nthe cooling is considerably reduced. We show that cooling to the ground state\nis possible also outside the Lamb-Dicke regime. We develop the model and use\nQuantum Monte Carlo calculations for specific examples. We show that a rate\nequation treatment is a good approximation in all cases.",
