The AG Weinelt studies ultrafast dynamics in quantum materials initiated by ultrashort optical 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 have a strong background and reputation in state-selective and spin-sensitive time- and angle-resolved photoemission techniques. Beyond our laboratory-based research, we established new experimental infrastructure at the FemtoSlicing facility of the Synchrotron Source BESSY II (Helmholtz-Zentrum Berlin) and are building a new end station for FLASH. With this new state-of-the-art experimental equipment for time-resolved X-ray scattering and absorption we study state- and element-specific dynamics. Our research focuses on the established CRC/TRR Ultrafast Spin Dynamics, the new CRC Heterostructures of Molecules & 2D Materials, and the new Cluster of Excellence for Chiral Electronics. We are FU partners in the Berlin Joint Laboratory on Ultrafast X-ray Science (BerLUXS) and the German-Eastern European Laboratory for Energy Materials Research (GELEM) at the Helmholtz Zentrum Berlin.
Job description:
AG Weinelt is searching for a postdoc in the field of Ultrafast Spin and Electron Dynamics, who is experienced in performing time-resolved X-ray spectroscopy experiments at large-scale facilities, in particular Free Electron Lasers. As a postdoc in the BMBF project “SPINFLASH” centered at the Free Electron Laser in Hamburg, you will work on setting up and developing a THz-pump / X-ray probe experiment at FLASH. You will take part in beamtimes at FLASH, BESSY II Femtoslicing, and other large-scale facilities. You have experience working in a team of scientists including doctoral and master’s students. The position serves to provide scientific qualification in the field of research and the acquisition of skills in the field of ultrafast carrier and spin dynamics in solid state materials. You will become an associated member of CRC/TRR Ultrafast Spin Dynamics and the Excellence Cluster for Chiral Electronics.
Requirements:
Doctorate in physics
Desirable:
Experiments at synchrotrons and FELs, Computer control of measuring equipment and data acquisition, Ultrafast dynamics, X-ray spectroscopy, Ultra-high vacuum technology.
