QUTRANPY

Aim

This program allows to perform quantum transport calculations using tight binding models with a user friendly interface

How to install

The program has been developed to run in Linux machines. Execute the script "install" to compile all the necesary libraries, which will also add to your PATH the folder ../bin, where the script qutranpy is present.

For using this program in Windows and Mac, the easiest solution is to create a virtual machine using Virtual Box, installing a version of ubuntu in that virtual machine, and following the previous instructions.

Capabilities

• Quantum transport using Landauer-Buttiker formalism in electronic systems
• Quantum transport between normal metals and superconductors using non-equilibrium Green's functions
• Possibility of including spin-orbit coupling, magnetism and superconductivity
• Allows to sweep in a variety of parameters of the Hamiltonian, the length of the scattering region and the energy of the incident electron
