摘要：

We have studied a single Vortex with the staggered flux (SF) core based on the SU(2) slave-boson theory of high T-c superconductors. We find that, whereas the center in the vortex core is a SF state, as one moves away from the core center a correlated staggered modulation of the hopping amplitude chi and pairing amplitude Delta becomes predominant. We predict thatlin this region the local density of states exhibits staggered modulation when measured on the bonds, which may be directly detected by STM experiments.
