Topological Order in Gutzwiller Projected Wave Functions for Quantum Antiferromagnets
Tao Li, Hong-Yu Yang
We study the topological order in RVB state derived from Gutzwiller projection of BCS-like mean field state. We propose to construct the topological excitation on the projected RVB…
The Hellberg-Mele Jastrow factor as a variational wave function for the one dimensional XXZ model
Hong-Yu Yang, Tao Li
We find the Jastrow factor introduced by Hellberg and Mele in their study of the one dimensional t-J model provides an exceedingly good variational description of the one dimension…
Variational study of the one dimensional t-J model
Hong-Yu Yang, Tao Li
We find the Gutzwiller projected Fermi sea wave function(GWF) has the correct phase structure to describe the kink nature of the doped holes in the ground state of the one dimensio…
Spinon-Holon Recombination in Gutzwiller Projected Wave Functions
Hong-Yu Yang, Tao Li
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 respo…
On the Origin of the Tunneling Asymmetry in the Cuprate Superconductors: a variational perspective
Hong-Yu Yang, Fan Yang, Yong-Jin Jiang +1
Through variational Monte Carlo calculation on Gutzwiller projected wave functions, we study the quasiparticle(qp) weight for adding and removing an electron from a high temperatur…
