EQuUs v4.9.146 comes with the following functionalities:

  • Spin and charge transport in normal/superconducting systems
  • Multi-terminal structures
  • Automatically generated predefined lattice structures
  • Inclusion of overlap matrices.
  • SVD regularization of the leads.
  • Interface for the SIESTA package
  • Inclusion of custom Hamiltonians (molecular structures)
  • Automatic transformation to the Bogoliubov-de Gennes model
  • Efficient numerical components for large-scaled non-trivial structures using EQuUs MKL component
  • Automatic magnetic field and gauge transformation
  • DC Josephson current
  • DC Josephson current in multi-terminal structures
  • Self-consistent framework for electron density based functionals. (self-consistent charge distribution, electron-electron interaction, s-type pair potential)
  • Transverse momentum resolved computations.
  • Computing the energy and the wave function of the eigenstates.
