€ 2325 - € 2972 per maand


Do you have a master’s degree in theoretical or mathematical physics, mathematics or a related subject? We are seeking a PhD candidate for a research project on 'Resurgence and Renormalons in Quantum Field Theory'. The goal of the project is to apply the ideas of resurgence in the setting of quantum field theories, in particular to the study of renormalon effects in QFTs and in particle physics phenomenology. The four-year project will be supervised by dr Marcel Vonk and prof. Eric Laenen.

You will be employed at the Institute of Physics of the University of Amsterdam and will spend roughly half of your time at its Institute for Theoretical Physics and half at nearby Nikhef, the Dutch national institute for subatomic physics.

Dr Marcel Vonk, the first supervisor, is a mathematical physicist at the Institute for Theoretical Physics in the String Theory and Mathematical Physics groups. Dr Vonk is an expert on the mathematical theory of resurgence and its applications to physics.

Prof. Eric Laenen, the second supervisor, is a theoretical physicist at the Institute of Physics and Nikhef. Prof. Laenen is an expert on perturbative approaches to quantum field theory.

The physics and mathematics community in Amsterdam is large and lively. Besides the institutes mentioned above, you will be able to interact with scientists at the Korteweg de Vries Institute for Mathematics and the many other physics groups and institutes that are located at the Amsterdam Science Park.

What are you going to do?

Resurgence techniques form a very useful tool to study nonperturbative physics. Many applications have been in toy models, but the aim of this project is to apply resurgence to realistic and semi-realistic quantum field theories. Renormalons, a type of divergent behavior in the perturbative approach to quantum field theories point to nonperturbative aspects and form a highly interesting area for further development using the mathematics and physics of resurgence.

In this position you will:

  • study and contribute to the theory of resurgence;
  • apply these ideas in a QFT setting;
  • understand their phenomenological implications;
  • be embedded in the UvA-Institute of Physics as well as nearby Nikhef;
  • interact with many other researchers (e.g. mathematicians) at Amsterdam Science Park;
  • assist in the teaching of undergraduates.


  • An (almost) completed master’s degree in theoretical physics, high energy physics, mathematics, or a closely related field;
  • a strong mathematical background as well as a good knowledge of quantum field theory, with some affinity with programming;
  • ability to start the position in September 2020 (an earlier or later starting date can be discussed);
  • a dedication to teaching at the undergraduate and graduate levels;
  • fluency in English, both written and spoken.


A temporary contract for 38 hours per week for the duration of 4 years (initial appointment will be for a period of 18 months and after satisfactory evaluation it will be extended for a total duration of 4 years) and should lead to a dissertation (PhD thesis). We will draft an educational plan that includes attendance of courses and (international) meetings. We also expect you to assist in teaching undergraduates and master students.

The salary, depending on relevant experience before the beginning of the employment contract, will be €2,325 to €2,972 (scale P) gross per month, based on full-time employment (38 hours a week). These amounts are exclusive 8 % holiday allowance and 8,3 % end-of-year bonus. A favourable tax agreement, the ‘30% ruling’, may apply to non-Dutch applicants. The Collective Labour Agreement of Dutch Universities is applicable.
