Abstract
We study the fermionic states of the antiferromagnetically ordered vortex cores predicted to exist in the superconducting phase of the proposed SO(5) model of strongly correlated electrons. Our model calculation gives a natural explanation of the recent STM measurements on BSCCO, which in surprising contrast to YBCO revealed completely insulating vortex cores.Keywords
