Phys. Rev. B 55, 6735–6738 (1997)Symmetry-breaking Skyrmion states in fractional quantum Hall systemsReceived 16 October 1996; published in the issue dated 15 March 1997 We calculate in an analytical fashion the energies and net spins of Skyrmions in fractional quantum Hall systems, based on the suggestion that Skyrmion states are spontaneously LZ and SZ symmetry-breaking states. The quasihole-Skyrmion state with a charge -e/3 around ν = 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. © 1997 The American Physical Society URL:
