Understanding high-Tc cuprates based on the phase string theory of doped antiferromagnet
Z. Y. Weng, D. N. Sheng, C. S. Ting
We present a self-consistent RVB theory which unifies the metallic (superconducting) phase with the half-filling antiferromagnetic (AF) phase. Two crucial factors in this theory in…

Marshall sign and the doped model
Z. Y. Weng, D. N. Sheng, Y. C. Chen
Marshall sign as a sole source of sign problem hidden in an antiferromagnet is explored under doping. By tracking the Marshall sign, a zero spectral weight is revealed in the d…
