Postdoc in Quantum Many-Body Physics with Ultracold Rb-Sr Mixtures and RbSr Molecules

Faculty/Services:  Faculty of Science
Educational level:  PhD
Function type:  Academic Staff
Closing date:  31 January 2024
Vacancy number:  12088



Are you a eager to push quantum simulation to new levels in a lively, international research group? Our Strontium Quantum Gases Group is offering a PhD position on our RbSr project. Our group is headed by Prof. Florian Schreck and is part of the Quantum Gases & Quantum Information (QG&QI) cluster at the Institute of Physics (IoP) of the University of Amsterdam (UvA). We exploit ultracold Sr for quantum simulation, quantum sensing, and quantum computing. Our group is part of QuantumDelta NL, which brings quantum technology closer to applications by collaborating with industry, startups and users.


What are you going to do?


You will be exploring quantum physics with ultracold RbSr ground-state molecules [Science 357, 1002 (2017)]. Those molecules have a large electric dipole moment and a significant magnetic moment, which is in contrast to all other ultracold molecules created to date. These properties enable new ways to tune anisotropic long-range interactions by applying electromagnetic fields. We recently have created weakly-bound RbSr molecules and your first goal will be to transfer them into their absolute ground state using laser pulses. Next you will research how to master the interactions between molecules and use them for quantum simulations of long-range interacting many-body systems. Yet another intriguing research avenue is to explore strongly-interacting Rb-Sr Bose-Fermi mixtures, which bring beyond Hubbard-model lattice physics into reach by exploiting element-specific optical lattices.


What do you have to offer?


You have:

  • a PhD in experimental ultracold atom or trapped ion physics;
  • motivation to work with an ambitious and nice team in a challenging, but rewarding, research field.
  • good command of English


Our offer


We offer a temporary employment contract for 38 hours per week for an initial period of 1 year. Based on performance the contract can be extended for another 2 years. The preferred starting date  is as soon as possible.

The gross monthly salary, based on 38 hours per week and dependent on relevant experience, ranges between € 3,226 to € 5,090 (scale 10). This does not include 8% holiday allowance and 8,3% year-end allowance. A favourable tax agreement, the ‘30% ruling’, may apply to non-Dutch applicants. The Collective Labour Agreement of Universities of the Netherlands is applicable.


Besides the salary and a vibrant and challenging environment at Science Park we offer you multiple fringe benefits:

  • 232 holiday hours per year (based on fulltime) and extra holidays between Christmas and 1 January;
  • multiple courses to follow from our Teaching and Learning Centre;
  • multiple courses on topics such as leadership for academic staff;
  • multiple courses on topics such as time management, handling stress and an online learning platform with 100+ different courses;
  • 7 weeks birth leave (partner leave) with 100% salary;
  • partly paid parental leave;
  • the possibility to set up a workplace at home;
  • a pension at ABP for which UvA pays two third part of the contribution;
  • the possibility to follow courses to learn Dutch;
