Observation of chiral and slow plasmons in twisted bilayer graphene

Nature, Published online: 04 May 2022; doi:10.1038/s41586-022-04520-8

Two new plasmon modes are observed in macroscopic twisted bilayer graphene with a highly ordered moiré superlattice, the first being the signature of chiral plasmons and the second a slow plasmonic mode around 0.4 electronvolts.
