The v=1 Quantum Hall edge with a realistic potential
arXiv:cond-mat/0203407 · doi:10.1103/PhysRevB.66.165308
Abstract
We study the softening of the edge modes of the compact ferromagnetic v=1 Quantum Hall edge as the strength of the confining potential decreases. To obtain a realistic potential we use a displaced background charge plane. We find a phase transition into a spin textured edge for g<0.012 (g is the ratio betwen the Zeeman and Coulomb energies).
