Abstract

We have performed an exact diagonalization study of up to N=12 interacting electrons on a disk at filling ν=13 for both true Coulomb interaction, and the V1 Haldane short-range interaction for which Laughlin wave function is the exact solution. For the Coulomb interaction and N>~10 we find persistent radial oscillations in electron density, which are not captured by the Laughlin wave function. Our results strongly suggest formation of a chiral striped phase at the edge of the fractional quantum Hall systems. The amplitude of the charge density oscillations decays slowly, only as a power law with the distance from the edge. Thus the spectrum of edge excitations is likely to be affected.
