Quantum Numbers of Hall Effect Skyrmions | Chetan Nayak

18 May 1995 | Subject: | cond-mat hep-th | Abstract: | By carefully considering a family of wave functions for Skyrmions in simple quantum Hall states, whose members are labelled by a non-negative integer and which properly generalizes the traditional Laughlin quasiparticle, we argue that the spin of this particle has a fractional part related in a universal fashion to the properties of the bulk state, and propose a direct experimental test of this claim. We argue directly also for the fractional charge and fractional quantum statistics of these particles. We show that certain spin-singlet quantum Hall states can be understood as arising from primary polarized states by Skyrmion condensation. | Source: | arXiv, cond-mat/9505081 | Services: | Forum | Review | PDF | Favorites |
