a, The honeycomb lattice with energy offset between the A sites (closed circles) and B sites (open circles) can be tuned into a lattice of dimers with stronger tunnelling bonds along one direction (thicker grey lines). The inset shows cuts of the potential along a dimer before (light blue line) and after the quench (dark blue line) together with the initial density profile (red area). b, Experimental images for 10 µs, 90 µs after the quench. A lattice vector corresponds to 10.9 pixels with a magnification of M = 93(1). c, Time evolution of the density distributions within one dimer after the quench from the simulation (left) and from the experiment (right, cut of 1 pixel width). For a realistic comparison we have broadened the simulation results with a Gauss filter of 76 nm width and added an offset (see Methods) (middle). The arrows mark the evolution times shown in b.
