PhD position in ultrafast dynamics of Mott insulators in Zürich

The Ultrafast Dynamics Group (Prof. Steven Johnson) in the Department of Physics of ETH Zürich has an open PhD position.

The aim of this project is to investigate ultrafast dynamics in Mott insulators, in particular GaTa4Se8. A volatile drop in electrical resistivity can be triggered in these materials either following the application of an electric field for a few tens of microseconds or, crucially, after exposure to an ultrashort THz pulse. This PhD position is full-time.

Our goal is to characterize the resulting low resistivity phase as well as the nature of the ultrafast transition leading to it, using a combination of ultrafast spectroscopy techniques in the THz, mid-infrared and x-ray frequency ranges.

This project will be based in Prof. Steven Johnson’s Ultrafast Dynamics Group at ETH Zürich and conducted under Dr Elsa Abreu’s leadership. X-ray measurements will take place at large-scale facilities both in Switzerland and abroad.

You hold a Master’s degree preferably in physics, alternatively in material sciences. A strong background in condensed matter physics is required, and previous experience with ultrafast optical or x-ray experiments is a definite plus. The candidate must demonstrate proficiency in oral and written English and must be enthusiastic, creative and self-motivated. 

ETH Zurich is a family-friendly employer with excellent working conditions. You can look forward to an exciting working environment, cultural diversity and attractive offers and benefits.
