Hollowing out single ions with high-power lasers

We numerically investigate the dynamics and radiation of multiple charged i ons in intense laser fields. The large magnetic component of the applied la ser intensities in association with high electron velocities close to the i onic core results in an extremely high Lorentz force in the vicinity of the ionic core. As a consequence me observe an essentially vanishing mean expe ctation value of the electronic wave packet distinctively around the ionic core. At the end of the laser pulse the hollowing-out of the ion is reverse d and gives rise to X-ray radiation.
