A general relation between stacking order and Chern index: a topological map of minimally twisted bilayer graphene
S. Theil, M. Fleischmann, R. Gupta +4
We derive a general relation between the stacking vector describing the relative shift of two layers of bilayer graphene and the Chern index. We find $C = ν- \text{sign}\…
Dislocation and node states in bilayer graphene systems
D. Weckbecker, R. Gupta, F. Rost +2
We investigate the electronic structure of realistic partial dislocation networks in bilayer graphene that feature annihilating, wandering, and intersecting partial lines. We find…
Straintronics beyond homogeneous deformation
R. Gupta, F. Rost, M. Fleischmann +2
We present a continuum theory of graphene treating on an equal footing both homogeneous Cauchy-Born (CB) deformation, as well as the microscopic degrees of freedom associated with…
Tuning topological surface magnetism by bulk alloying
N. Klier, S. Sharma, O. Pankratov +1
Deploying an analytical atomistic model of the bulk band structure of the IV-VI semiconductors we connect the spin structure of the topological surface state to the crystal field a…
Going beyond k.p theory: a general method for obtaining effective Hamiltonians in both high and low symmetry situations
N. Ray, F. Rost, D. Weckbecker +5
We provide a method for the generation of effective continuum Hamiltonians that goes beyond the well known k.p method in being equally effective in both high, and low (or no) symme…
