Up to 4 years post-doc position at the department of physics, Rennes University, France

Ultrafast Optical and X-ray investigation of Transition Metal Compounds

Application deadline: not before October 1st 2020 and until a suitable candidate is found
Net Salary: ~ 2 000 € to 3 000 € / month (depending on experience)

What we offer: We have a fully funded up to four years postdoc position in our group to work on
ultrafast photoinduced phenomena in transition metal compounds, using UV-VIS optical
spectroscopy (inhouse, Rennes) and X-ray scattering and spectroscopy (Free Electron Laser).
Close collaboration with theory will be integral part of the project. The postdoc position is financed
by the ANR (National Research Agency). The project aims at understanding the photophysics of
transition metals to a new level of detail thanks to a joint experimental and theoretical research
program involving three laboratories and two countries (IPR in Rennes, ICR in Marseille,
SwissFEL in Villigen). Ultrafast optical spectroscopy and X-ray techniques will be pushed to time
resolutions approaching 10 fs. Quantum models will be used to solve time dependent Schrodinger
equation to follow the photoinduced wavepacket motion and dispersion along different excited state
trajectories. The latter will be experimentally controlled by wavelength tunable femtosecond laser

What we look for: The ideal candidate should have a PhD degree and a solid hands-on experience
with ultrafast techniques (pump-probe, femtosecond lasers, OPAs). Previous experience in XFEL or
synchrotron experiments is a plus. Skills in data analysis are mandatory. Good oral and written
communication in English, as well as aptitude for teamwork are essential. The candidate will
closely collaborate with an international team of experimental and theoretical researchers.
Job tasks: The successful candidate will:

● help to operate and develop the inhouse femtosecond optical spectroscopy setup.
● Perform diagnostics of excitation pulses
● Perform, analyze and interpret inhouse experiments
● Take an active role in experiments at FEL and synchrotron facilities
● Analyze FEL data (X-ray diffraction, absorption, emission)
● Write scientific articles and disseminate the results at conferences

Salary and employment conditions: The contracts retirement contributions and give right include
full social security coverage and unemployment benefits. Post-doc have no teaching obligations.
Rennes is a medium size French city less 1.5 hour train ride from Paris, offering a relaxing lifestyle
with many cultural and sport activities.

Who we are: The “Materials and Light Group” is a research group based at the Institute of Physics
of the University of Rennes 1 and CNRS. We focus our research on phenomena in molecules and
materials by using optical the out of equilibrium and X-ray techniques with femtosecond resolution.
