Local enhancement of spin and orbital antiferromagnetism around a single vortex in high-temperature superconductors

Abstract: In a simple model we investigate three competing orders: d-wave superconductivity, spin and orbital antiferromagnetism (AF) in the vicinity of a single vortex in a cuprate superconductor. We find that when the potential for the orbital AF V d is comparatively small, the spin-density-wave (SDW) order has an enhancement at the vortex core center, and the "d-density-wave" (DDW) order exhibits a rather weak behavior around the core and vanishing small away from the core. However, when V d becomes large, globally, … Show more

“…We have used large scale real-space Bogoliubov de-Gennes mean field simulations, a method that has been widely used to study competing phases [26][27][28][29][30][31][32][33][34][35][36] . This is the best available microscopic method to study vortex lattices, as the orbital field introduces a sign problem in quantum Monte Carlo simulations.…”
