Abstract

Along with  a brief introduction to the phenomenon of the  integer quantum Hall effect, I will briefly review  edge reconstruction due to Coulomb interactions and changes in the smoothness of the edge potential. Then I will describe some recent work where we show how exchange interactions can cause a switching of the spin of the edge modes, causing like spins to come close to each other.
