Scientific Codes

  • CP2K
    CP2K is a quantum chemistry and solid state physics software package that can perform atomistic simulations of solid state, liquid, molecular, periodic, material, crystal, and biological systems. CP2K provides a general framework for different modeling methods such as DFT using the mixed Gaussian and plane waves approaches GPW and GAPW.

  • Environ
    ENVIRON is a module to handle environment effects in first-principles condensed-matter simulations, in particular for applications in surface science and materials design.
    Groups: Goedecker, Marzari / Project: DD3
  • FWP finite-size corrections
    This script calculates the finite-size corrections of total energies and single-particle energy levels involving defect states with built-in ionic polarization in supercell calculations. The method accounts on an equal footing for the screening of the electrons and of the ionic polarization charge arising from the lattice distortions. These corrections allow one to achieve accurate optical transition energies and single-particle defect levels without requiring computationally prohibitive system-size scalings.

  • Glosim
    Glosim is a Python package to compute similarities between molecules and structures.
    Group: Ceriotti / Project: HP4
  • IrRep
    IrRep is a python code that calculates the symmetry eigenvalues and irreducible representations of bands computed with state-of-the-art Density Functional Theory codes such as VASP, Quantum Espresso or Abinit and others. It is applicable to materials in any of the 230 space groups and double groups preserving time-reversal symmetry. IrRep is a powerful tool to systematically analyze the connectivity and topological classification of bands, as well as to detect insulators with non-trivial ground states, following the Topological Quantum Chemistry formalism or calculating the symmetry-based indicators.

  • NESSi
    This library allows efficient and accurate calculations based on non-equilibrium Green's functions.
    Group: Werner / Project: DD5
  • QML
    QML is a Python2/3-compatible toolkit for representation learning of properties of molecules and solids. QML is not a high-level framework where you can do model.train(), but supplies the building blocks to carry out efficient and accurate machine learning on chemical compounds. As such, the goal is to provide usable and efficient implementations of concepts such as representations and kernels. GitHub link

  • Quantum ESPRESSO
    Quantum ESPRESSO is an integrated suite of Open-Source computer codes for electronic-structure calculations and materials modeling at the nanoscale. It is based on density-functional theory, plane waves, and pseudopotentials. GitHub link
    Group: Marzari / Project: PP6
  • Sirius
    SIRIUS is a domain-specific library with GPU backend designed to accelerate plane-wave electronic structure codes such as Quantum ESPRESSO and Exciting, or to be used as a Quantum Engine in programs using localized basis sets. GitHub link

  • Sketch-map
    Sketch-map is a non-linear dimensionality reduction algorithm that is particularly well suited for examining high-dimensionality data that is routinely produced in atomistic simulations. It transforms the connectivity between a set of high dimensionality data points in 2-dimension while putting higher importance to proximity matching. While the similarity between a pair of atomic structures can be measured in various ways, we used SOAP-REMatch kernel, developed in our group for this purpose.

  • WannierBerri
    WannierBerri is a python code for efficient Wannier interpolation and tight-binding calculations of bandstructure, Berry curvature, orbital magnetic moments and other properties of Bloch bands, as well as evaluation of integrated quantities, like the intrinsic anomalous Hall conductivity (AHC), anomalous Nernst effect (ANE), nonlinear Hall effect, and other transport and optical effects.

  • WannierTools
    WannierTools is an open-source software based on tight-binding model for analysis physics properties of crystal materials including energy band topology (Z2, Chern number, looking for Weyl points, Berry phase, Berry curvature, Wilson loop, surface states etc.), ordinary magnetoresistance, Landau level spectrum, etc.
    Group: Troyer / Project: VP1
  • Wannier90

    Wannier90 is an open-source code for generating maximally-localized Wannier functions (WFs) and using them to compute advanced electronic properties. Wannier90 supports various algorithms, including the original Marzari-Vanderbilt localisation and  Souza-Marzari-Vanderbilt disentanglement schemes; symmetry-adapted and selectively-localized WFs; and the SCDM method to avoid defining initial projection. In addition, Wannier90 exploits the real-space localisation of WFs to obtain spectral and Fermi-surface properties at high-resolution in the Brillouin zone. These include: density of states, band structures, Fermi surfaces, Berry phase properties and transport properties.
