Optically-dressed resonant Auger processes induced by high-intensity x rays

Abstract

We have unveiled coherent multiphoton interferences originating from different quantum paths taken by the Auger electron induced by a high-intensity x-ray/XUV pulse under the presence of a strong optical field. These interferences give rise to a clear signature in the angle-resolved Auger electron spectrum: an asymmetry with respect to the energy of the Auger decay channel. In order to illustrate this effect we have considered the resonant Auger decay of the transition $2p^5\leftrightarrow 1s^{-1}2p^6$ in Ne${}^{+}$. The simulations show that these interferences are very sensitive to the parameters of the x-ray and optical fields.
