Who We Are

The Weinelt research group studies ultrafast dynamics at solids and their surfaces initiated by ultrashort laser pulses. This includes single and collective quasiparticle dynamics to unravel signatures of non-equilibrium dynamics and phase transitions in the transient electronic structure. We develop a fundamental understanding of processes such as ultrafast demagnetization and magnetic switching by following electronic scattering, spin transport, and magnon excitation with complementary experimental methods. We have a strong background and reputation in state-selective and spin-sensitive time- and angle-resolved photoemission techniques. Our research is funded by DFG through Transregio CRC “Ultrafast Spin Dynamics” (-), CRC “Heterostructures of Molecules and Two-Dimensional Materials” ( – ) and the Cluster of Excellence “Center for Chiral Electronics” (start ).
Beyond our laboratory-based research, we are the FU Berlin partner for two joint laboratories with the Helmholtz-Zentrum Berlin, BERLUXS (Berlin Laboratory for Ultrafast X-ray Slicing), and GELEM (German-Eastern European Laboratory for Energy and Materials Research). We established new experimental infrastructure around the FemtoSpeX Slicing beamline of the Synchrotron Source BESSY II (HZB) and build currently a new endstation for THz pump/ X-ray probe experiments at BL11 of FLASH (Free Electron Laser in Hamburg). With this new state-of-the-art experimental equipment for time-resolved X-ray scattering and absorption, we study state- and element specific spin dynamics.

What You Can Expect in Your New Role

Investigation of the electronic structure and dynamics in 2D materials and magnetic layer systems using spin- and time-resolved photoelectron spectroscopy. Participation in the research projects of the working group listed under “Who We Are”. You will be primarily responsible for the further development of a momentum microscope and the experiments conducted there. This also includes the commissioning of a spin detector. You will participate in conducting experiments, analyzing data, writing publications, and supervising master's and doctoral students.
