The two-leg t-J ladder: a spin liquid generated by Gutzwiller projection of magnetic bands
Abstract
The ground state of the two-leg Heisenberg ladder is identified as an 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.
