摘要

We solve numerically the relativistic Liouville equation for the phase space density of an atom in a uniform static magnetic field and a laser field. If the cyclotron frequency that is associated with the magnetic field is tuned slightly above a multiple or a fraction of the frequency of the laser field, the electron's dynamics becomes resonant and its velocity can approach the speed of light. We compare the spatial electron distributions at these resonances with those obtained from the corresponding non-relativistic calculations and find the formation of stable ring-shaped distributions at the multiple resonances. The fractional resonances are characterized by figure-eight or propeller-shaped distributions.
