Welcome to the KITE v1.0.

KITE is an open-source Python/C++ software suitable for Large-Scale Tight-Binding (TB) quantum transport calculations. The code is shipped with the following capabilities:

• Quantum Transport: longitudinal and transverse DC conductivities at zero and finite temperature;
• Optical Properties: AC longitudinal conductivity;
• Optical Properties: nonlinear optical susceptibility;
• Electronic Structure: high-resolution density of states (DoS) in clean and disordered systems;
• Electronic Structure: local density of states and ARPES;
• Special Features: automated magnetic field in 2D;
• Special Features: lattice perturbations (e.g., strain) and 'disorder cell' concept for implementation of multi-orbital/-bond impurities;
• Algorithms: ultra-high-resolution CPGF full spectral (DoS);
• Algorithms: high-resolution CPGF full spectral (finite temperature response functions);
• Algorithms: ultra-high-resolution CPGF single-shot (zero temperature DC conductivity)

For further details on the algorithm and the implementation please consult ArXiv:1910.05194

For understanding the main functionalities of the code, how to setup a model and evaluate the KITE target functions, we suggest you to check the tutorial Getting Started. More advanced calculations are explained in Examples. After downloading the repository, you can find the python scripts used throughout the tutorial under the examples folder.
