We consider single-electron tunneling through antidot states using a Coulomb-blockade model, and give an explanation for $h/2e$ Aharonov-Bohm oscillations, which are observed experimentally when the two spins of the lowest Landau level form bound states. We show that the edge channels may contain compressible regions, and using simple electrostatics, that …
