Plaquette valence bond state in spin-1/2 J1-J2 XY model on square lattice
Y. -H. Chan, Hong-Chen Jiang, Y. -C. Chen
We studied the ground state phase diagram of spin-1/2 J1-J2 XY model on the square lattice with first- J1 and second-neighbor J2 antiferromagnetic interactions using both iDMRG and…
Revisit Phase Separation of the Two-Dimensional model by the Power-Lanczos Method
C. T. Shih, Y. C. Chen, T. K. Lee
The power-Lanczos (PL) method is one kind of Green's function Monte-Carlo simulation, which is improved by Lanczos iterations. The ground state energies of strongly-correlated mode…
Long-range order and low-energy spectrum of diluted 2D quantum AF
A. L. Chernyshev, Y. C. Chen, A. H. Castro Neto
The problem of diluted two-dimensional (2D) quantum antiferromagnet (AF) on a square lattice is studied using spin-wave theory. The influence of impurities on static and dynamic pr…
Phase Separation of the Two-Dimensional t-J model
C. T. Shih, Y. C. Chen, T. K. Lee
The boundary of phase separation of the two-dimensional t-J model is investigated by the power-Lanczos method and Maxwell construction. The method is similar to a variational appro…
