Diploma/Master student –  Electron dynamics control via radiation reaction

Next-generation multipetawatt laser systems such as the Extreme Light Infrastructure (ELI) and at the Exawatt Center for Extreme Light Studies (XCELS) are expected to reach intensities beyond 1022 W/cm2 at their focus, paving the way to novel investigations in the realm of ultrastrong-field electrodynamics. At such ultrahigh intensity, for example, an electron undergoes an extreme acceleration and becomes ultrarelativistic in a fraction of the laser period therefore emitting large amounts of electromagnetic radiation. As a consequence, the back-action on the electron's motion of the radiation emitted by the electron itself, namely the radiation reaction force, becomes important, and may noticeably alter the electron dynamics. A deep understanding of RR effects is therefore crucial for the design and the interpretation of experiments at ultrahigh intensities.

In addition, it has been recently shown that the radiation reaction force can be employed to control the electron dynamics in the interaction of an electron colliding head-on with a bichromatic laser laser pulse, by tuning the relative phase between the two frequency components [Tamburini et al., Phys. Rev. E 89, 021201(R) (2014)]. A similar effect is also predicted in the interaction of an electron with a carrier-envelope-controlled superintense laser pulse, such as those that can be generated by employing the relativistic mirror technique [Tamburini et al., Phys. Rev. Lett. 113, 025005 (2014)].

We are seeking a master student to investigate the features of the electron dynamics in the interaction with a carrier-envelope-tunable few-cycle laser pulse. The student is expected to carry out both analytical calculations and numerical simulations starting with an existing code. Fluency in English and a solid background in theoretical physics are required, a sound knowledge of Fortran or C/C++ is desirable.

The research project will be carried out at the Max Planck Institute for Nuclear Physics (MPIK), Saupfercheckweg 1, 69117 Heidelberg, Germany. Please send your application including CV by email to Matteo Tamburini. Equal opportunity is a cornerstone policy of the Max Planck Society (MPG), and women as well as disabled people are particularly encouraged to apply. This position is open and applicants are invited as of now.
