Introduction

Wannier90 is a computer package written in Fortran90. It is used to obtain maximally-localised Wannier functions in order to calculate bandstructures, Fermi surfaces, dielectric properties, sparse Hamiltonians and many things besides.

Many electronic structure codes have an interface to Wannier90, including Quantum ESPRESSO, Abinit, VASP, Siesta, Wien2k, Fleur, OpenMX, and GPAW. There are several post-processing codes that are able to use the output of Wannier90 for further analysis and calculation.
