The topological quasi-flat band configuration. (A) The spatial density 
, (B) the contribution of the initially populated edge states 
, and (C) the contribution of the initially populated bulk states 
. In all the figures, 
and 
. The total number of particles is 
, whereas the number of initially populated edge states is 
. Note the dispersionless nature of the occupied bulk states, which highly improves the detection of the edge-state signal.
