The file contains tight binding band structures of twisted multi-layer graphene superlattices. Each key describes a layered assembly using a string-based notation. For example, the string G/G@1.08 describes a bilayer of graphene with twist angle of 1.08. The symbols / and @ are used to describe the binary operations of the vertical stacking of a layer or layered (sub)structure on another, and counterclockwise rotation of a layer or layered (sub)structure by some angle about the stacking direction (in degrees; assuming the same absolute coordinate system), respectively. The notation is described in detail in G. A. Tritsaris, Y. Xie, A. M. Rush, S. Carr, M. Mattheakis, and E. Kaxiras. arXiv:1910.03413 (2019) Each tight binding band structure is described by a list (electronic bands) of lists (eigenenergies). We use 60 points to sample the Brillouin zone along the direction connecting the high-symmetry k-points Γ, M, and K, and therefore each band is described by 60 eigenenergies.
