Abstract
We investigate theoretically Zitterbewegung behavior of Dirac oscillator after the excitation by a short laser pulse. With the help of the time-dependent perturbation theory, the dipole moments and the corresponding electric fields are calculated. We simulate the asymptotic limiting cases in relativistic and non-relativistic regimes with the quantum optic experiment and the results indicate that the ZB motion and the electromagnetic radiation tend to vanish in both limits. Further we analyze the Fourier frequency spectra of ZB motion.
