Figure 6

The moving lattice depth is ramped to (a) V′=0.25 ER, (b) V′=0.5 ER and (c) V′=1.0 ER in the first 60 ms and then keep this value for the following 40 ms. The white lines indicate the centre of the small dipole osicllation from which the band minimum is determined. The driving frequency is |Δω|=5.21 ER.
