Python Tight Binding (PythTB)

PythTB is a software package providing a Python implementation of the tight-binding approximation. It can be used to construct and solve tight-binding models of the electronic structure of systems of arbitrary dimensionality (crystals, slabs, ribbons, clusters, etc.), and is rich with features for computing Berry phases and related properties.
