Tunable SU(4) Symmetry in Bilayer Graphene
The charge carriers in bilayer graphene have both spin and valley degeneracy. Because of its unique electronic structure, valley symmetry in this material is connected to layer symmetry, which can be broken experimentally with a transverse electric field. Together with the coupling of spin to extern...
