| Abstract: | The improved Linear Combination Operator method is adopted to study the ground state of a slow moving optical polaron in N-dimensional polar crystals. The analytical expressions of the ground state energy and effective mass of a polaron, average virtual phonon number around the electron are derived for both of strong and intermediate coupling(covering weak coupling ) limits. corre-sponding numerical results are also obtained for the whole coupling region. |
