Latest stable release (27 February 2019): Wannier90 (v3.0.0) [gzipped-tar]

Please note that:

Electronic Structure Codes

Wannier90 should be used in conjunction with an electronic structure code for calculating the eigenstates of the Hamiltonian operator. Currently, as far as we are aware, the following electronic structure codes interface to Wannier90:

Additional packages interfaced to Wannier90

  • EPW – An open-source F90/MPI code which calculates properties related to the electron-phonon interaction using density-functional perturbation theory (DFPT) and maximally-localised Wannier functions.
  • Gollum – A program written in Matlab that computes the electrical and thermal transport properties of multi-terminal nano-scale systems. The program can compute transport properties of either user-defined systems described by a tight-binding (or Huckel) Hamiltonian, or more material-specific properties of systems composed of real atoms described by DFT Hamiltonians.
  • NanoTCAD ViDES – An open-source Python code for simulating nanoscale devices through the self-consistent solution of the Poisson and the Schrodinger equations by means of the non-equilibrium Green’s function (NEGF) formalism.
  • Z2Pack – A tool for calculating topological invariants. The method is based on tracking the evolution of hybrid Wannier functions, which is equivalent to the computation of the Wilson loop.
  • WannierTools – An open-source software package for novel topological materials.
  • Sisl – An API for manipulating, constructing and creating tight-binding matrices in a standard and uniform way, which also provides an interface to the TBtrans code for large-scale NEGF transport calculations.

Visualisation Programs

The following programs should be installed to visualise the output of Wannier90:

  • gnuplot is used to plot band structures. It is available for many operating systems and is often installed on unix/Linux distributions by default
  • XCrySDen is used to visualise crystal and molecular structures, Wannier functions and Fermi surfaces. It is available for Unix/Linux, Windows (using cygwin) and OSX. To correctly display files from Wannier90, use XCrySDen version 1.4 or later.
  • VESTA is another program that can be used to visualise structures and Wannier functions, in particular when outputted in Gaussian cube format.

MLWFs and the LAPW formalism

Technical notes on the calculation of MLWF within the LAPW formalism are now available, courtesy of Prof. Michel Posternak [PDF].
