| 内容記述 | Density-functional calculations for the sub-cycle ultrafast dynamics in the dielectrics are presented. The calculations employing the time-dependent density functional theory (TDDFT) predicts the reversible change of the optical properties under an intense laser field, which can be attributed to the time-resolved dynamical Franz-Keldysh effect (DFKE). The time-resolved DFKE has been observed by the pump-probe experiment in attosecond timescale. An analytical formulation is also derived by parabolic two-band model. This model calculation well reproduces the computational and experimental results. From the computational and the analytical approaches, the polarization dependence of the DFKE can be also predicted. | |||||
