摘要：

The ground state of the two-leg Heisenberg ladder is identified as a resonating-valence-band-RVB type spin liquid, which is generated by Gutzwiller projection of tight-binding bands with flux pi per plaquet. Explicit trial wave functions for the magnon and hole excitations are formulated in terms of spinons and holons. The spinon-holon bound state is shown to violate P and T. This is interpreted as a manifestation of fractional statistics.
