| 英文摘要 | The dynamic effect of band electrons is investigated in the presence of ac and dc electric fields. The explicit solutions for the quasienergies and the Floquet states are obtained exactly in a one band approximation. The results depend on the number-theoretical property of the matching ratio omega(D)/omega, where omega is the ac frequency and omega(D) is the frequency of the Stark ladders associated with the dc field. If the matching ratio is rational, all the Floquet states are extended in general. If it is irrational, the states are exponentially localized, except for the cases where the matching ratio is extremely well approximated by rationals (i.e., a Liouville number). |
