Skyrmions in the moore-read state at 谓=52
Physical Review Letters 104:8 (2010)
Abstract:
We study charged excitations of the non-Abelian Moore-Read liquid at a filling factor 谓=52, 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 e/4 quasiholes to bind into Skyrmions of charge e/2. We show that Skyrmion formation is further promoted by disorder, and argue that this can lead to a depolarized 谓=52 ground state in realistic experimental situations. We comment on the consequences for the activated transport. 漏 2010 The American Physical Society.Resources Required for Topological Quantum Factoring
