Supplementary code for "Topology of the generalized Brillouin zone of one-dimensional models"

This file contains the Mathematica code for producing all figures in the journal article "Topology of the generalized Brillouin zone of one-dimensional models" (DOI: 10.1103/7cnd-r7q4), which describes the topology of the generalized Brillouin zone and the occurrence of disconnected generalized Brillouin zones of one-dimensional models.
