Spinon-Holon Recombination in Gutzwiller Projected Wave Functions
arXiv:cond-mat/0604489
Abstract
The Gutzwiller projection is shown to induce nontrivial correlation between the spinon and the holon in the slave Boson theory of the model. We find this correlation is responsible some subtle differences between the slave Boson mean field theory and the Gutzwiller projected wave function(GWF), among which the particle-hole asymmetry in the quasiparticle weight calculated from the GWF is a particular example.
