摘要：

We study the electronic structure of the vortex core in the cuprates using the U(1) slave-boson mean-field wave functions and their Gutzwiller projection. We conclude that there exists local orbital antiferromagnetic order in the core near optimum doping. We compare the results with those of BCS theory and analyze the spatial dependence of the local tunneling density of states.
