Abstract
We study charged excitations of the non-Abelian Moore-Read liquid at a filling factor , allowing for spin depolarization. Using a combination of numerical studies, and taking account of nonzero well widths, we find that at a sufficiently low Zeeman energy it is energetically favorable for charge quasiholes to bind into Skyrmions of charge . We show that Skyrmion formation is further promoted by disorder, and argue that this can lead to a depolarized ground state in realistic experimental situations. We comment on the consequences for the activated transport.
