Topological edge-reconstruction occurs in hole-conjugate states of the fractional quantum Hall effect. The frequently studied filling factor, ν  = 2/3, was originally proposed to harbor two counter-propagating modes: a downstream v  = 1 and an upstream v  = 1/3. However, charge equilibration between...
