Abstract:

Relaxation through phonon exchange of adsorbates on the surface of a crystal is considered. The effect of the thermal phonon field on the time evolution of the adsorbate is taken into account with finite memory time reservoir theory. Also, the low-intensity photon absorption profile is evaluated. The spectrum has a sharp cutoff at the Debye frequency of the crystal and a memory induced extra resonance.
