EIT Ground State Cooling Scheme of Yb-171(+) Based on the (S1/2P1/2)-S-2-P-2 Cooling Transition

We propose a method for EIT ground state cooling of Yb-171+ ion, which involves three light fields with detuning on a MHz scale. The steady-state mean vibrational quantum number is calculated to be less than 0.005. Efficient cooling is achievable in a motional-mode frequency range of 2 (1.5 +/- 0.5 MHz).
