Anderson tower of states and nematic order of spin-1 bosonic atoms on a 2D lattice
L. de Forges de Parny, H-Y. Yang, F. Mila
We investigate the structure of the spectrum of antiferromagnetically coupled spin-1 bosons on a square lattice using degenerate perturbation theory and exact diagonalizations of f…
Effective Spin Couplings in the Mott Insulator of the Honeycomb Lattice Hubbard Model
H-Y. Yang, A. F. Albuquerque, S. Capponi +2
Motivated by the recent discovery of a spin liquid phase for the Hubbard model on the honeycomb lattice at half-filling, we apply both perturbative and non-perturbative techniques…
Effective spin model for the spin-liquid phase of the Hubbard model on the triangular lattice
H-Y. Yang, A. Laeuchli, F. Mila +1
We show that the spin liquid phase of the half-filled Hubbard model on the triangular lattice can be described by a pure spin model. This is based on a high-order strong coupling e…
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…
