An optimized ion trap geometry to measure quadrupole shifts of ¹⁷¹Yb⁺ clocks

Batra N^{1, 2}, Sahoo B K³, De S^{1, 2, †,}

Spatial dependence of the fractional electric quadrupole shifts Δν_Q/ν_o for the (a) E2 and (b) E3 clock transitions of ¹⁷¹Yb⁺. The quadrupole trapping potential produces a constant shift (gray). The spatial dependency in the shift along the radial (red) and axial (blue) directions arise from the anharmonic components k > 2 of Φ^(k).
