One variant of this phenomenon can be used to tune the electronic properties of boron nitride nanotubes from nearly insulating to metallic. Another variant of this phenomenon is induced by interference of standing laser waves to trap atoms of a Bose-Einstein condensate loaded into an optical lattice. Schrdinger's third article from his 1926 series of papers presented his perturbation theory treatment of this effect's modification of the Balmer and Lyman series. Along with van der Waals broadening and resonance broadening, this effect can produce pressure broadening of spectral lines. In addition to the giant version and the AC or Autler-Townes form of this effect, it exhibits variants that are linear and quadratic in the applied field. FTP name this shifting and splitting of spectral lines due to an external electric field, the analogue of the Zeeman effect.
