Spinon-Holon Recombination in Gutzwiller Projected Wave Functions

TL;DR

This paper demonstrates that Gutzwiller projection induces significant spinon-holon correlations in the $t-J$ model, explaining discrepancies between mean field theory and projected wave functions, especially in quasiparticle properties.

Contribution

It reveals how Gutzwiller projection creates nontrivial spinon-holon correlations, clarifying differences from slave Boson mean field results in the $t-J$ model.

Findings

Gutzwiller projection induces spinon-holon correlation.

Correlation affects quasiparticle weight asymmetry.

Differences between mean field and GWF are explained.

Abstract

The Gutzwiller projection is shown to induce nontrivial correlation between the spinon and the holon in the slave Boson theory of the $t-J$ 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.
