TL;DR
This paper explores the SO(5) theoretical model to explain insulating vortex cores in high-temperature superconductors, aligning with recent experimental STM observations in BSCCO.
Contribution
It provides a theoretical explanation for insulating vortex cores in high-$T_c$ materials using the SO(5) model, connecting theory with recent experimental findings.
Findings
The SO(5) model predicts antiferromagnetically ordered vortex cores.
The model explains the insulating nature of vortex cores observed in STM experiments.
It offers a unified framework for understanding vortex core states in high-$T_c$ superconductors.
Abstract
We study the fermionic states of the antiferromagnetically ordered vortex cores predicted to exist in the superconducting phase of the newly 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.
