| 内容記述 | Numerical pump-probe simulations for the sub-cycle transient spectroscopy of thin film diamond under intense few cycle pulse laser field is reported. The electron dynamics is calculated by the time-dependent Kohn-Sham equation. Simultaneously, the propagation of electromagnetic field is calculated by the Maxwell equation. Our result shows that the modulation of the reflectivity, transmission, and absorption around the optical gap do not coincide with the field amplitude of the pump laser. The phase shift of the modulation with respect to the pump field depends on the pump intensity and probe frequency. The modulation of the reflectivity is sensitive to the choice of the exchange-correlation potential, and dynamical effect of the mean-field in meta-GGA potential. |
