Qutranpy

Interactive program to perform quantum transport calculations by means of the Landauer and scattering matrix formalism, in a two terminal geometry. The Hamiltonians of leads and scattering region can be modified, adding exchange fields, mass, spin-orbit coupling or superconductivity.

Features

Quantum transport in tight binding model
Superconducting leads
Sweep in different parameters
Adiabatic transport (experimental)

Project Samples

Main interface of Qutranpy, with the different parameters that can be changed

Example of the evolution of the transmission as a function of the length of a tunnel barrier (gapped central part)

Example where the right lead is a topological superconductor, reflected in the zero bias peak conductance as weak coupling

Fabry-Perot oscillation for a junction with different fermi velocities in the leads and the central part

spin precession between two ferromagnetic leads, with a central region with spin-orbit coupling
