Relativistic Quantum Dynamics in Intense Laser Fields

摘要: We investigate the relativistic dynamics of electrons in intense laser fields. Examples both free and bound electron are discussed using approach appropriate for each particular case, i.e., either classical mechanics or quantum mechanics. The algorithm numerically solving Dirac equation is explained detail before showing results that were obtained electronic wave packets interaction with In case former, we discuss Volkov point out features such as Lorentz contraction, spin non-dipole effects. A sevenfold charged oxygen ion a counterpropagating beam illustrates latter demonstrates method generating high-energy electron—nucleus collisions. Furthermore, briefly outline procedure equations motion arbitrary electromagnetic special field configuration (that radially polarized beam) considered an example. fields result from Maxwell's calculate energy may be gained by single this configuration.
