Skyrmions and edge spin excitations in quantum Hall droplets

Condensed Matter 2009-10-28 v1

Abstract

We present an analysis of spin-textures in Quantum Hall droplets, for filling factors ν1\nu \simeq 1. Analytical wavefunctions with well defined quantum numbers are given for the low-lying states of the system which result to be either bulk skyrmions or edge spin excitations. We compute dispersion relations and study how skyrmions become ground states of the Quantum Hall droplet at ν1\nu \gtrsim 1. A Hartree-Fock approximation is recovered and discussed for those spin textures.
