GROUP THEORY SYMBOL

GTCrystalField

GTCrystalField[group,lmax]
gives the crystal field Hamiltonian for a certain group up to a maximal angular momentum quantum number lmax.

DetailsDetails

  • In the framework of perturbation theory, the influence of the crystal field can be expressed in terms of a crystal field potential .
  • The crystal field potential can be expanded into spherical harmonics.
  • The following options can be given:
  • GOFastFalseControls the input validation
    GOHarmonics"Complex"Selects, which kind of spherical harmonics are used
  • See: W. Hergert, M. Geilhufe, Group Theory in Solid State Physics and Photonics. Problem Solving with Mathematica, chapter 7.4
