a, Illustration of the extended preparation protocol: after executing step 1 as in Fig. 2a, in step 2, ΔV is adiabatically tuned such that the atomic population in the second band is relocated towards the p orbitals in the deep wells. b, Exact band calculations of the momentum distribution for the Bloch function \({\Phi }_{{{\rm{K}}}_{\Delta }}\) for dominant population of p+ orbitals. The red dashed circles highlight the resulting absence of certain higher-order Bragg peaks, in contrast to Fig. 2b. c, Momentum spectra for extended preparation protocol at various holding times, analogous to those in Fig. 2c.
