clocks. Here we present a novel 3D cooling method which leverages the mHz-linewidth clock
state in 171 Yb in a 1D optical lattice to achieve longitudinal cooling, Tz < 575 nK, and radial sub-recoil
temperatures Trad < 165 nK ≈ 0.4 Trecoil. We present two potential dark state mechanisms leading to
sub-recoil temperatures. The ability to control the radial temperature distribution complements
our previous work with adiabatic rapid passage, allowing the preparation of atoms in arbitrary
lattice bands. Together these methods allow for improved control of the atomic distribution
in both the radial and longitudinal modes, a necessary step for characterization of the lattice
light shift at or below the 10-19 decade including measurement of the M1/E2 contribution to the
lattice light shift.
