a Numerically calculated dynamical phase (Eq. (2)) modulo 2π × 102 for S-P, S-D, and P-D interferometric loops (with 100 kHz, 190 kHz, and 143 kHz drives, respectively) as a function of lattice depth for TB = 10.7 ms estimated with static band energies; only the P-D loop exhibits a magic condition at nonzero \({V}_{0}^{\rm M}\approx 8.85\,{E}_{\rm R}\). b Output population imbalance at TB = 10.70 ms as a function of lattice depth. Vertical dashed (dotted) lines indicate the lattice depths chosen for force measurements far from (close to) the magic condition. c, d Imbalance as a function of applied force away from (c) and close to (d) the magic condition at the aforementioned lattice depths.
