Symmetry-breaking skyrmion states in fractional quantum Hall systems

Abstract

We calculate in an analyical fashion the energies and net spins of skyrmions in fractional quantum Hall systems, based on the suggestion that skyrmion states are spontaneously LZL_Z and SZS_Z symmetry-breaking states. The quasihole-skyrmion state with a charge e/3-e/3 around ν\nu = 1/3, where the ground state is known as a spin-polarized ferromagnetic state, is found to exist even in high magnetic fields up to about 7 T for GaAs samples.
