Description
We propose a theory for doped antiferromagnet based on a bosonic resonating-valence-bond (RVB) state with incorporating the phase string effect. Both antiferromagnetic (AF) and superconducting phase transitions occur naturally within such a bosonic RVB phase. Two distinct metallic regions -- underdoping and optimum-doping -- are also found to be a logic consequence, whose unique features explain the recent neutron-scattering measurements in cuprates.
