This code is used to simulate an exciton (electron-hole pair) on a 3D lattice in presence of disorder

This code represents a self-consistent tight-binding model for an exciton in a cubic 3-dimensional lattice with disorder. The main quantities that can be extracted by this code are the exciton binding energy and its spatial localization. For more information about the theory and the algorithm, please consult:
