Interference Effects in Electron-Positron Pair Creation by the Interaction of a Bichromatic Laser Field and a Nucleus — •Sven Augustin and Carsten Müller — Max-Planck-Institut für Kernphysik, Heidelberg

We investigate the creation of electron-positron pairs in the superposition of a nuclear Coulomb field and a two-colour laser field of high intensity. Herein our focus lies on quantum interference effects which may arise if the two laser frequencies are commensurate.

The interference manifests in the angular distributions of the created particles and the total pair production rates. In addition, the influence of the relative phase between the two laser modes is studied.
