    • Gauge-origin independent calculations of electric-field-induced second-harmonic generation circular intensity difference using London atomic orbitals 

      Anelli, Marco; Ringholm, Magnus; Ruud, Kenneth (Journal article; Tidsskriftartikkel; Peer reviewed, 2017)
      We present the first gauge-origin independent calculations of the circular intensity difference (CID) in electric-field-induced second-harmonic generation (EFISHG), including all contributions up to the electric-quadrupole–magnetic-dipole level. A recursive, open-ended response theory framework in combination with the use of London atomic orbitals allows us to ensure gauge-origin independent results. ...

    • The origin dependence of the material constants: the permittivity and the inverse permeability 

      Anelli, Marco; Jonsson, Dan Johan; Fliegl, Heike; Ruud, Kenneth (Journal article; Tidsskriftartikkel; Peer reviewed, 2015-05-26)
      New derivations of origin-independent expressions for the electric permittivity are presented, starting either from the response function of the current density that defines the absorption coefficient, or from the off-resonance single-photon scattering amplitude that leads to the Kramers–Heisenberg dispersion formula. The resulting expression for the permittivity is compared with earlier work ...
