Spin-orbit-driven quarter semimetals in rhombohedral graphene

This study reports the observation of spin-orbit-driven quarter semimetals in rhombohedral multilayer graphene, where strong correlations and proximitized spin-orbit coupling induce spontaneous symmetry breaking and a hysteretic anomalous Hall effect, ultimately enabling a magnetic-field-tuned phase transition to Chern insulators.
