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
