Lorentz oscillator model

Electrons are bound to the atomic nucleus analogously to springs of different strengths, AKA springs that are not isotropic, AKA anisotropic.

The Lorentz oscillator model describes the optical response of bound charges. The model is named after the Dutch physicist Hendrik Antoon Lorentz. It is a classical, phenomenological model for materials with characteristic resonance frequencies (or other characteristic energy scales) for optical absorption, e.g. ionic and molecular vibrations, interband transitions (semiconductors), phonons, and collective excitations.^[1]^[2]
