Artificial Edge in An Optical Lattice

Caption

Artificial edge in an optical lattice (blue), filled with an ultracold quantum gas that consists of 'spin-up' particles (red) and 'spin-down' particles (green). Along the edge - and only there - 'spin-up' particles can only flow to the left, and 'spin-down' particles can only flow to the right.
