"PhD position in AMO Physics - QuEST for APV"

We are searching for a motivated and interested PhD-student, with a degree in physics or related topics or with experience in quantum technology, spectroscopy, and/or laser physics, who wishes to work with us in the international and stimulating environment of the joint Quantum Metrology group at LaserLaB Amsterdam.

This project aims to develop a new experimental apparatus that enables quantum enhanced sensing in trapped barium ions for tests of electroweak theory. At the basis of the project lies a unique high-precision radio frequency ion trap in which single Ba+ ions will be confined and cooled to their motional ground state. With optical standing waves the individually ions will be addressed to drive an extremely weak parity forbidden transition. In order to detect the signals from driving such a weak transition, quantum entangled states will be used that reject external perturbations. Based on measurements of atomic parity violation in Ba+, its electroweak charge will be extracted to test the electroweak theory at low energies with unprecedented precision and search for possible signal that may hint towards new physics.

During the PhD, you will engage with various aspects of experimental physics, including ultrahigh vacuum, CAD design, optics and lasers, electronics, and scientific programming.

Requirements
Master in physics or related topics
Affinity for atomic, molecular, and optical physics.
Preferably some experience with experimental techniques
Most important is that you are bright, enthusiastic, work well in a team, are eager to learn, and of course that you are enthusiastic about this intriguing project!

As a university, we strive for equal opportunities for all, recognising that diversity takes many forms. We believe that diversity in all its complexity is invaluable for the quality of our teaching, research and service. We are always looking for talent with diverse backgrounds and experiences. This also means that we are committed to creating an inclusive community so that we can use diversity as an asset.

We realise that each individual brings a unique set of skills, expertise and mindset. Therefore we are happy to invite anyone who recognises themselves in the profile to apply, even if you do not meet all the requirements.

Conditions of employment
Fixed-term contract: 1 year.
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 € 3.059,00 (PhD) and maximum € 3.881,00 (PhD) gross per month in the fourth year, for a full-time employment
an employment contract of initially 1 year. If there is sufficient perspective, this will be extended to a total of 4 years. Your dissertation at the end of the fourth year forms the end of your employment contract.
We also offer you attractive fringe benefits and arrangements. 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
discount on (and occasionally exclusive access to) theater performances and courses at the Griffioen Cultural Center

Employer
Vrije Universiteit Amsterdam
QMLA group in the Department of Physics and Astronomy

The Quantum Metrology and Laser Applications group at LaserLaB, Vrije Universiteit Amsterdam, is a very international group, consisting of some 20 strongly collaborating senior and junior scientists. The group focuses on precision measurements of atomic and molecular systems, using advanced laser techniques as well as techniques to cool the motion of atoms and molecules. For this, they use the joint infrastructure at LaserLaB, with a variety of lasers ranging from ultrastable to ultrafast, connected to atomic clocks and frequency comb lasers. The goals are to test fundamental theories of physics (like Quantum Electrodynamics), to determine fundamental constants (like the proton-electron mass ratio), and to search for physics beyond the Standard Model, such as fifth forces and extra dimensions.
