| Abstract | We propose a series of paired spin-singlet quantum Hall states, which exhibit a separation of spin and charge degrees of freedom. The fundamental excitations over these states, which have filling fraction $\nu=\frac{2}{2m+1}$ with $m$ an odd integer, are spinons (spin-$\frac{1}{2}$ and charge zero) or fractional holons (charge $\pm \frac{1}{2m+1}$ and spin zero). The braid statistics of these excitations are non-abelian. The mechanism for the separation of spin and charge in these states is topological: spin and charge excitations are liberated by binding to a vortex in a $p$-wave pairing condensate. We briefly discuss related, abelian spin-singlet states and possible transitions. |
