Researcher Profile: First Stage Researcher (R1)

Country: France

Application Deadline: 4 Jul 2025 - 23:59 (UTC)

Type of Contract: Temporary

Offer Description

This PhD thesis, supervised by N. Keller, R. Bertoni, and C. Mariette, focuses on time-resolved light-matter interaction and X-ray diffraction studies at large-scale infrastructures such as ESRF. The candidate will be trained in optical spectroscopy and X-ray diffraction techniques, working mainly at the Institut de Physique de Rennes and partly at ESRF. The team has extensive ultrafast laser laboratories with various time-resolved setups. Daily activities involve collaboration with team members in the laser lab.

Skills required include deep knowledge in optics and solids-state physics, experience in optical spectroscopy, programming skills (preferably in Python), and good communication skills. The work environment is international, and presentation of results at conferences is encouraged. Employment conditions include salary, social security, and unemployment benefits. The position is based in Rennes, a city offering a relaxed lifestyle with cultural and sports activities.

The research team, part of the Materials and Light Department at the University of Rennes, studies ultrafast phenomena in materials and molecules using optical and X-ray techniques. The team is part of the IRL-DYNACOM involving French and Japanese universities.

The scientific project addresses phase change materials (PCM) with applications in neuromorphic computing. It explores photoinduced phase transitions in ferroelectric and antiferroelectric perovskite thin films, characterized by optical and THz absorption spectroscopy, second-harmonic generation, and time-resolved X-ray diffraction. The goal is to understand ultrafast dynamics of phase transitions induced by optical and THz excitations.

References include studies on optical and magnetic switching, quantum paraelectric transitions, and ultrafast spectroscopy techniques.
