pygra
DESCRIPTION:
Python library to perform electronic structure calculations with tight binding models in different types of lattices and different dimensionalities. It allows to include different terms in the Hamiltonian as sublattice, exchange field or magnetic field. Provides functions to calculate different Green functions, band structure, density of states, transport using Landauer formula, topological invariants, etc.
Features
- 0d,1d,2d tight binding
- Green functions and Landauer quantum transport
- Topological invariants
- Band structure and density of states
Audience
Science/Research, Education
Programming Language
Fortran, Python
