dc.descriptionMarshall 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 $Z$ is revealed in the doped antiferromagnetic system. $Z=0$ is caused by a phase string induced by the ``bare'' hole. By eliminating such a phase string through nonlocal transformations, a non-perturbative scheme is obtained. It is argued that this formalism provides a unique way to get access to the real ground state of the doped $t-J$ model for both one- and two-dimensions.
