PhD Position in Experimental Condensed Matter Physics: Development of Dual Free Electron Laser Spectroscopy

Are you a motivated Master’s student looking to pursue a PhD and ready to dive into the depths of experimental physics? Would you like to harness the power of dual free electron lasers to unveil new insights? If so, come and join our team at HFML-FELIX and the Max-Planck Center in Nijmegen (Netherlands) and collaborate with researchers at the Fritz Haber Institute in Berlin (Germany) to illuminate uncharted scientific territories.

The free electron lasers (FELs) at HFML-FELIX are versatile and highly sought-after sources of intense picosecond light pulses, useful for investigating dynamic processes in matter. Your research project will focus on designing and testing a new type of optical experiment using two synchronised FELs in a novel operation mode currently being commissioned at HFML-FELIX. This set-up aims to simultaneously use infrared and THz light to explore fundamental dynamic processes in solids that were previously inaccessible. Our FELs provide short intense pulses of radiation in the whole spectral range of low-energy physics covering the full quasiparticle spectrum from magnons and phonons to Cooper pairs and polarons.

In parallel, dual FEL optical experiments are being developed and tested at the Fritz Haber Institute in Berlin, where you will collaborate with another PhD candidate. This project is partially funded by the Max Planck – Radboud University Center for Infrared Free Electron Laser Spectroscopy, where a cohort of PhD candidates collaborate in person on specific topics.

As a PhD candidate, you will have the chance to develop valuable skills by mentoring students, participating in international conferences, and collaborating with leading researchers. You will also work with external users on related experiments and serve as a teaching assistant in Radboud University's teaching programme, with a teaching load of up to 10% of your working time.

• We will give you a temporary employment contract (1.0 FTE) of 1.5 years, after which your performance will be evaluated. If the evaluation is positive, your contract will be extended by 2.5 years (4-year contract).
• You will receive a starting salary of €2,901 gross per month based on a 38-hour working week, which will increase to €3,707 in the fourth year (salary scale P).
• You will receive an 8% holiday allowance and an 8,3% end-of-year bonus.
• You will receive extra days off. With full-time employment, you can choose between 30 or 41 days of annual leave instead of the statutory 20.

Work and science require good employment practices. This is reflected in Radboud University's primary and secondary employment conditions. You can make arrangements for the best possible work-life balance with flexible working hours, various leave arrangements and working from home. You are also able to compose part of your employment conditions yourself, for example, exchange income for extra leave days and receive a reimbursement for your sports subscription. And of course, we offer a good pension plan. You are given plenty of room and responsibility to develop your talents and realise your ambitions. Therefore, we provide various training and development schemes.

HFML-FELIX is a large‐scale research infrastructure. Its in‐house research programmes focus on chemistry and physics, fostering interdisciplinary research.
