Etymology

Named after Swiss physicist Gregory Wannier (1911–1983).

Noun

Wannier function (plural Wannier functions)

1. (physics) Any of a set of orthogonal functions used in solid-state physics; they are the localized molecular orbitals of crystalline systems.

     The Wannier functions (WF)^35,36 are the most localized orbitals within the valence-band and conduction-band subspaces. Hence we will use WF as ϕ_l in Eqs (1) and (2).
