New PhD and Postdoc positions available for research program to solve the Proton Radius Puzzle

We newly acquired funding from FOM/NWO for an integral research program that aims to solve the Proton Radius Puzzle and potentially find clues for new physics. The idea is to perform highly advanced laser precision spectroscopy in four systems: H2, HD+, He+ and He. For this we have several PhD and postdoc positions available from 1 January 2017. You can find the general information about the program here.

For more specific information about the 4 projects involved, you can use the following links:
Project A1 and A2: precision spectroscopy on He+ ions and H2 molecules
Project B: precision spectroscopy on HD+ ions
Project C: precision spectroscopy on H2/D2/T2 molecules  
Project D: precision spectroscopy on 4He and 3He metastable atoms  


PhD and Postdoc positions available due to the ERC Advanced Grant of Kjeld Eikema

Recently (March 2016) Kjeld Eikema was awarded an ERC Advanced Grant for “The Proton Size Puzzle: Testing QED at Extreme Wavelengths”.

There are several PhD (4 year) and Postdoc (2-3 year) positions available starting in the summer of 2016 and later. We are looking for enthusiastic and ambitious people; please look here for more information.

PhD position connected to the ERC-Advanced grant of Wim Ubachs

Within the ERC-Advanced grant project of Wim Ubachs on “Physics Beyond the Standard Model with Molecules” there is an opening for a PhD student under full employment by VU University for 4 years.

1 PhD position on: Molecular beam experiments in H2 in search for physics beyond the Standard Model
In future there may also be an opening for a PostDoctoral fellow on this subject. Interested young scientists with a PhD in this field may already send in applications.



PhD positions at the Advanced Research Center for Nanolithography working with VU physicists: 
Contact:  Prof. W. Ubachs (, Dr. S. Witte ( and Prof. K. Eikema (

The Advanced Research Center for Nanolithography (ARCNL) focuses on the fundamental physics involved in current and future key technologies in nanolithography, primarily for the semiconductor industry. ARCNL’s program is intimately connected with the interests of ASML. A significant part of the initial program is devoted to the physics that is central in the generation of high intensities of extreme ultraviolet light and its use in nanolithography. In the course of time, ARCNL’s program will evolve to keep the center at the frontier of research in the area of nanolithography.
