Unconventional superconductivity in graphene (2018-2025)
Twisted bilayer graphene launched the field of moiré superconductivity in 2018, followed by a wave of graphene-based superconducting systems. Rhombohedral graphene emerged in 2025 with chiral superconductivity evidence — a discovery that broke the moiré requirement, using flat multilayer stacks instead.
Rhombohedral graphene became a new platform for studying unconventional superconductivity, including magnetic-field-boosted states reported in 2026.
The material's tunability positions it as a testbed for pairing mechanisms, with implications for topological quantum computing via Majorana fermions.
The anomalous metal study extends this program, showing rhombohedral graphene hosts both zero-resistance and finite-resistance superconducting phases — adding a new dimension to the platform's capability.
