Dynamical Process of Charge Transfer in Fullerene C₆₀

We consider lattice relaxation in doped C₆₀ using the tight-binding model applied to a single C₆₀ molecule. To simulate the dynamical evolution processes of string polaron in charged C₆₀, we use a classical dynamical method where all the tangential collective coordinates are chosen. The nonlinear response time of lattice relaxation can be obtained in view of the present theory.
