Caption

The lattice potential consists of individual dimers. The lattice position is sinusoidally modulated in one direction at two frequencies (purple and orange arrows). Depending in the occupancy in the lattice, atoms can pick up a phase (green arrows) in a density-assisted tunnelling process (brown arrow), compared to a single-particle hopping process (blue arrow).
