Staggered Currents in the Vortex Core
Jung Hoon Han, Qiang-Hua Wang, Dung-Hai Lee
Abstract
We study the electronic structure of the vortex core in the cuprates using the U(1) slave-boson mean-field wavefunctions and their Gutzwiller projection. We conclude that there exists local orbital antiferromagnetic order in the core near optimal doping. We compare the results with that of BCS theory and analyze the spatial dependence of the local tunneling density of states.
