摘要：
We study, numerically, the dynamical behavior of an electron in a two-site nonlinear system driven by de and ac electric field separately. We also study, numerically, the effect of electric field on single static impurity and antidimeric dynamical impurity in an infinite one-dimensional chain to find the strength of the impurities. Analytical arguments for this system have also been given. [S0163-1829(98)06108-6].
