Abstract
We consider the low-lying states of a class of tight-binding models related to the parity- and time-reversal-breaking chiral-spin liquid, which describes a magnetically frustrated Mott insulator. In precise analogy with the soliton excitations of polyacetylene, the presence of a midgap state bound to topological disruptions of the chiral order leads to neutral, spin-1/2 spinors and charge-e, spinless holons.
