About the Position

We are seeking a highly motivated PhD researcher to join our team at Vrije Universiteit Amsterdam. As a PhD researcher in quantum metrology and spectroscopy, you will be part of a dynamic and international group focused on precision measurements of atomic and molecular systems.

Your primary responsibility will be to develop and implement novel quantum technologies for spectroscopy and metrology. This will involve working with advanced laser systems, cryogenic ion traps, and ultrahigh vacuum techniques. You will also be responsible for designing and conducting experiments to test fundamental theories of physics and determine fundamental constants.

To be successful in this role, you will need a strong background in atomic and molecular physics, as well as experience with experimental techniques and data analysis. You will also need to be able to work independently and as part of a team, with excellent communication and problem-solving skills.

About the Project

The project aims to measure the level structure of weakly-bound molecular states of H2+ with unprecedented accuracy using novel quantum technologies. This will involve developing a novel cryogenic ion trap for quantum-logic spectroscopy using H2+ (spectroscopy) and Be+ (logic) ions.

You will also be responsible for developing a continuous-wave laser system at 313nm to laser cool Be+ ions, which will then be used for sympathetic cooling of the molecular ions. The molecular ions will be selectively prepared by field-ionizing the optically excited molecular Rydberg states of H2 (we use extreme-UV light at 90nm, UV and visible laser light).

To guide the experimental developments and understand the measured spectra, you will dive into the details of the molecular Hamiltonian, advanced angular momentum theory, optical Bloch equations, laser cooling simulations, and many other topics.

About the Team

You will be part of a dynamic and international team of researchers and scientists at Vrije Universiteit Amsterdam. Our team is focused on precision measurements of atomic and molecular systems, using advanced laser techniques as well as techniques to cool the motion of atoms and molecules.

We are committed to creating an inclusive community that values diversity and internationalisation. We believe that diversity and internationalisation contribute to the quality of education, research, and our services.

What We Offer

We offer a challenging position in a socially engaged organisation. At VU Amsterdam, you contribute to education, research, and service for a better world. And that is valuable. So in return for your efforts, we offer you:

  • a salary of minimum € 2.872,00 (PhD) and maximum € 3.670,00 (PhD) gross per month, on a full-time basis. This is based on UFO profile PhD candidate. The exact salary depends on your education and experience.
  • a full-time position (1.0 FTE). Your employment contract will initially last 1 year. If there is sufficient perspective, this will be extended to a total of 4 years.

We also offer you attractive fringe benefits and regulations. Some examples:

  • A full-time 38-hour working week comes with a holiday leave entitlement of 232 hours per year. If you choose to work 40 hours, you have 96 extra holiday leave hours on an annual basis. For part-timers, this is calculated pro rata.
  • 8% holiday allowance and 8.3% end-of-year bonus
  • contribution to commuting expenses
  • optional model for designing a personalized benefits package
  • a wide range of sports facilities which staff may use at a modest charge
