| Abstract: | The exchange dephasing model is investigated theoretically. An equation of motion satisfied by a reduced density matrix for the observed high-frequency mode is derived by a cumulant perturbation expansion method up to fourth order. The calculation shows a temperature dependence of the width and shift of the spectral line. |
