Ultrafast Spin Transport Far from Equilibrium (2 Ph.D. positions)

Two theoretical Ph.D. positions are available in the field ultrafast electronic spin dynamics in metals and ferromagnets. In particular, we are interested in spin and charge transport far from equilibrium as it is induced by ultrashort optical pulses in metal-ferromagnet multilayer structures. While these structures are routinely fabricated and used in magneto-electronic transport, very little is known about the interplay of relaxation and transport processes on such ultrafast time scales. It is intended to apply kinetic methods such as Boltzmann transport equations and Monte Carlo trajectory simulations to obtain a comprehensive microscopic description of far-from-equilibrium transport in these structures. In parallel, simpler macroscopic transport equations will be developed and compared with the microscopic calculations. These processes will be investigated experimentally in close collaboration with theory in the framework of the same project in Spin+X. In particular, we are interested in excitation conditions with photon energies up to 6 eV, which are realized in the experimental part of this project and have not been studied so far.

Candidates are expected to have a solid background in theoretical solid state physics and experience with numerical methods. Knowledge in the field of optics, many-particle physics and plasma physics is appreciated.

The two theoretical Ph.D. student positions are supervised by Prof. B. Rethfeld and Prof. H. C. Schneider. Together with an experimental Ph.D. student they are part of project B03 in Spin+X, and will work closely together. We offer a lively, collaborative work environment, research and training at the forefront of a rapidly developing field, and the necessary high-performance computing infrastructure.
