Postdoc in experimental ultracold ion trap physics I

Aarhus University

The Department of Physics and Astronomy, Aarhus University, invites applications for a postdoc position in experimental ultracold ion trap physics.
The position is available from April 1, 2022 or as soon as possible thereafter
Job description
With the aim of setting up a novel experiment for the investigation of ultracold ion-atom interactions and “supermolecule” in the form of several ultracold atoms bound to a single ion by induced polarization forces, the research will initially be focused on sideband laser cooling of a single Ba+ ion to it motional quantum mechanical ground state in an existing cryogenically cooled linear Paul trap. The work will as well include optimization of key parameter for ultracold ion-neutral experiments, such as excess micromotion and motional heating rates. Alongside with these experimental challenges, the successful candidate will take part in designing the full ultracold ion-atom setup as well as take sympathetic ground state cooling of a range of smaller biorelevant ions such as charged amino acids.
The successful candidate will become a member of the Ion Trap Group and interact with researchers in the Center for Complex Quantum Systems (CCQ) ( at Aarhus University, which offers exciting opportunities for collaborative research at the interface of quantum optics, quantum information science and many-body physics.
Who are you?
Applicants should hold a PhD degree in physics. We are looking for talented and highly motivated applicants with a keen interest in quantum optics and quantum many-body physics. The successful candidate has a background in experimental cold ion or cold neutral atomic physics and has demonstrated an ability to carry out complex experiments. The applicant will have the possibility of advising PhD students in the group and to take on some teaching duties. We are aware of the under representation of minorities in physics, and welcome a diverse group of researchers who pursue early stage research with us.
Who we are
The successful candidate will be offered a lively and inspiring research environment through broad collaborative quantum science initiative CCQ at the department. The CCQ strives to create ideal conditions for the personal and scientific development of its postdocs, who are encouraged to participate in a variety of transferable skill courses, workshops and programs, offered by Aarhus University. Denmark is known for a high quality of life and a healthy work-life balance, and the city of Aarhus offers many recreational and cultural activities in a safe, tolerant and casual atmosphere.
The place of work is Ny Munkegade 120, DK-8000 Aarhus C, and the area of employment is Aarhus University with related departments. Please see for further information about the hosting Department for Physics and Astronomy.
Deadline for applications is February 1, 2022
Further information about the position and application procedure may be obtained from Michael Drewsen (

How to apply

Application procedure Shortlisting is used. This means that after the deadline for applications – and with the assistance from the assessment committee chairman, and the appointment committee if necessary, – the head of department selects the candidates to be evaluated. All applicants will be notified whether or not their applications have been sent to an expert assessment committee for evaluation. The selected applicants will be informed about the composition of the committee, and each applicant is given the opportunity to comment on the part of the assessment that concerns him/her self. Once the recruitment process is completed a final letter of rejection is sent to the deselected applicants. Letter of reference If you want a referee to upload a letter of reference on your behalf, please state the referee’s contact information when you submit your application. We strongly recommend that you make an agreement with the person in question before you enter the referee’s contact information, and that you ensure that the referee has enough time to write the letter of reference before the application deadline. Unfortunately, it is not possible to ensure that letters of reference received after the application deadline will be taken into consideration. Formalities and salary range Natural Sciences refers to the Ministerial Order on the Appointment of Academic Staff at Danish Universities under the Danish Ministry of Science, Technology and Innovation. The application must be in English and include a curriculum vitae, degree certificate, a complete list of publications, a statement of future research plans and information about research activities, teaching portfolio and verified information on previous teaching experience (if any). Guidelines for applicants can be found here. Appointment shall be in accordance with the collective labour agreement between the Danish Ministry of Finance and the Danish Confederation of Professional Associations. Further information on qualification requirements and job content may be found in the Memorandum on Job Structure for Academic Staff at Danish Universities. Salary depends on seniority as agreed between the Danish Ministry of Finance and the Confederation of Professional Associations. Aarhus University’s ambition is to be an attractive and inspiring workplace for all and to foster a culture in which each individual has opportunities to thrive, achieve and develop. We view equality and diversity as assets, and we welcome all applicants. Research activities will be evaluated in relation to actual research time. Thus, we encourage applicants to specify periods of leave without research activities, in order to be able to subtract these periods from the span of the scientific career during the evaluation of scientific productivity. Aarhus University offers a broad variety of services for international researchers and accompanying families, including relocation service and career counselling to expat partners. Read more here. Please find more information about entering and working in Denmark here. Aarhus University also offers a Junior Researcher Development Programme targeted at career development for postdocs at AU. You can read more about it here. The application must be submitted via Aarhus University’s recruitment system, which can be accessed under the job advertisement on Aarhus University's website.
