Reply to Neutral-fermion-soliton statistics in the short-range resonating-valence-bond state: A reevaluation

Abstract

Haldane and Levine have questioned our Berry phase analysis [Phys. Rev. B 35, 8865 (1987)] of the statistics of spinon and holon excitations in resonating-valence-bond states, claiming that the computations described in that work were performed incorrectly. We show below that their calculation does not disagree with ours, and in fact reproduces a limited subset of our results. We conclude with a brief caveat regarding the validity of the Berry phase approach to determining quasiparticle statistics. © 1989 The American Physical Society.
