Dynamic screening and collective excitation of an electron gas under intense terahertz radiation

Journal Article


Abstract


  • By using time-dependent wave functions for electrons under an intense laser, we calculated the charge-density fluctuation of an electronic system under a weak probing potential. The dielectric function of the system as a function of the laser frequency and intensity is derived. The spectrum of the collective excitation is calculated. The spectrum exhibits the contribution of various multiphoton processes.
