Two-dimensional Shiba lattices as a possible platform for crystalline topological superconductivity

Source data for the line plots of the main text and Extended Data figures of the paper "Two-dimensional Shiba lattices as a possible platform for crystalline topological superconductivity".

The repository contains the following python scripts:

    Open_Fig2_ED3.py -- Opens and plots the source data for Figure 2 and Extended Data Figure 3. This script uses the topographies_**.png files to display the position of the measured points in the lattice grid.

    Open_Fig3.py -- Opens and plots the source data for Figure 3. The distances corresponding to the rhombic and rectangular lattices are distinguished by different colours, and finally plotted together in terms of absolute distance from a reference site.

    Open_Fig4.py -- Opens and plots the source data for Figure 4. This plots the three ribbon spectra presented in Figure 4 of the main text, and then the open boundary conditions spectra of panel 4j.

    Open_ED1_ED2_ED5_ED6.py -- Opens and plots the source data for Extended Data Figures 1, 2, 5, 6.

Data files contained in the repository:

Note that each .txt file contains a brief description of the content at the beginning of the file. In addition, the meaning of each column and rows is explained. Each comment line is marked by a "#" at the beginning of the line, and the file can be uploaded by numpy.loadtxt("filename").
