Data underlying Figure 1 in the paper 'Topological states in honeycomb arrays of implanted acceptors in semiconductors'

FIg 1(a): each line consists of a list of comma-separated 8-tuples corresponding to the eight eigenvalues of the tight-binding Hamiltonian at a particular k-point. The eigenvalues are given on an array of 573 k-points uniformly spaced along the path Gamma-M-K-Gamma in the Brillouin zone, and then in an outermost loop the anistropy parameter delta is varied from 0.0 to 1.0 in steps of 0.2 (six values in all). <br> Fig 1(b): CSV file with each line contatining 96 comma-separated eigenvalues for the 24-atom wide strip with an armchair edge. The 2001 rows correspond to an array of k-points in the edge direction equally spaced from -pi to pi with an increment pi/1000. <br>
