Tight-Binding module in Python

Python Tight-Binding module

Python module to build up and solve Tight-Binding models.

tbee is written in fully vectorized Numpy.

tbee is composed of the following classes:

* lattice
* system
* plot
* propagation
* save

tbee main features:

* Complex lattice structures.
* Complex-valued onsite energies and hoppings.
* Hermitian and non-Hermitian Tight-Binding Hamiltonians.
* Sublattices.
* Hoppings defined by their type, tags, and angles.
* Any type of hoppings:

    * Neighbors hoppings,
    * Next-neighbors hoppings, 
    * Next-next-neighbors hoppings,
    * etc..

* Implementation of onsite energies and hopping patterns:

   * Dimerization defects.
   * Magnetic field.
   * Strain.
   * Hopping disorder.
   * Onsite disorder.

* Time propagation

tbee's Issues

No band support?

I don't see any example that can plot the band structure of a tight binding model. Does this means there are no such support?
