Researchers report observations of superconducting and anomalous metal phases in rhombohedral graphene.

What it means

This Nature paper reports the experimental observation of superconducting and anomalous metal phases in rhombohedral graphene stacked on a WSe₂ substrate. By tuning gate voltage and displacement field, the researchers map out a phase diagram showing regions of zero-resistance superconductivity and a distinct anomalous metallic state that deviates from conventional Fermi liquid theory. This work extends the study of strongly correlated physics in graphene-based systems.

Accuracy & sourcesGrounded

The claim comes directly from a peer-reviewed Nature article (doi:10.1038/s41586-026-11033-1), making it a primary source with high reliability. The work was previously available as a preprint on arXiv (2607.28425) and has now passed Nature's editorial and peer-review process.
