Tbee is a package providing a Python implementation, with heavy use of numpy vectorization, of Tight-Binding models. It can be used to build up and solve tight-binding models with complex-valued onsite energies and hoppings.
with a special emphasis on protected zero-modes induced by reduced chiral symmetry.
               
with a special emphasis on pseudo Landau levels and localized states induced by vacancy defects and negative couplings.
