| Abstract: | We investigate the vortex properties of a system where superconductivity competes with a staggered flux state. Such a competition has been proposed to be at the origin of the pseudogap phenomenon observed in the cuprates. We show that the presence of a staggered flux state is responsible for a substantial modification of the vortex structure and reversion of the vortex charge. We demonstrate that this scenario may explain some experimental results obtained with the help of scanning tunneling microscopy. |
