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.
Python module to build up and solve Tight-Binding models.
TBEE is written in fully vectorized Numpy.
TBEE is composed of the following classes:
TBEE main features:
Complex lattice structures.
Complex-valued onsite energies and hoppings.
Hermitian and non-Hermitian Tight-Binding Hamiltonians.
Hoppings defined by their type, tags, and angles.
Any type of hoppings:
- Neighbors hoppings,
- Next-neighbors hoppings,
- Next-next-neighbors hoppings,
Implementation of onsite energies and hopping patterns:
- Dimerization defects.
- Magnetic field.
- Hopping disorder.
- Onsite disorder.
