Unusual quantum states in six-layer graphene offer clues to superconductivity

https://phys.org/news/2026-10-unusual-quantum-states-layer-graphene.html

Summary:Unconventional correlated electronic states identified within stacked 6-layer rhombohedral graphene, shedding light on high-temperature superconductivity's microscopic origins. Spontaneous symmetry breaking/ exotic electronic phases observed tuning displacement electric fields across multilayer atomic structure. Tunable multi-layer graphene platforms provide clean experimental systems for investigating condensed matter flat-band superconductivity/ correlated electron dynamics.
