Truncated Atomic Plane Wave Method

Features

• Tight Binding Solver for TBG problem: TBPLW, TBFULL, TBSPARSE methods implemented.
• Continumm model solver.
• Different TB method band structure comparison.
• Moire potential Analysis.
• Valley Chern number calculation.
• $C_3$ symmetry constrain.

Dependent Module

Our development is based on SciPy, Numpy, Sklearn, Pybinding and matplotlib.
