• TITLE: Translational Motion of a Free Large Polaron and Broadening of Absorption Spectra

  AUTHORS: Vladimir Mukhomorov

  KEYWORDS: Large Polaron, Translational Motion, Canonical Transformation, Broadening, Absorption Spectra, Ammonia

  ABSTRACT: The translational motion of a large polaron as whole is analyzed in the context of its effect on the broadening of an absorption optical spectrum. It was open question how important the role of translational degrees of freedom and the corresponding velocities are on the broadening. The Bogolyubov method of canonical transformation of coordinates is formulated for a system of an electron and field, taking into account rigorous fulfillment of the conservation laws. Separation of variables is carried out for the coordinates describing the translational degrees of freedom and the electron oscillations in a polarization well. The equations obtained for the electronic states explicitly depend on the velocity of the free polaron as a whole. An estimate is made for free polaron in ammonia.
