A software package for calculating the electronic structure and topological properties of the tight-binding (TB) model.
To use the TopoTB package, you must specify the complete path to load the package through Get or Needs. Alternatively, if the TopoTB package is located in a directory included in $Path, you can directly call it using Get or Needs. For convenience, either of the following two lines of code can quickly open a directory contained in $Path, place the TopoTB package in it, and call it directly using Get or Needs.
SystemOpen[FileNameJoin[{$UserBaseDirectory,"Applications"}]]SystemOpen[FileNameJoin[{$BaseDirectory,"Applications"}]]Use the FindFile function to view the installation path of the TopoTB package and check if it is installed in the directory specified in $Path.
