PhD fellow in Quantum Optomechanics at the Niels Bohr Institute

Updated: about 1 month ago
Deadline: 04 Jul 2021

We are looking for highly motivated, excellent candidates with a master’s degree in physics or related fields, to advance our research in the field of quantum optomechanics.

Project description
The Quantum Optomechanics group at the Niels Bohr Institute specializes in measurement, control and conversion of motional quantum states. We have pioneered mechanical systems with exceptional coherence which allow reaching new regimes in terms of sensitivity and efficiency when it comes to measuring the smallest forces and displacements.

The goal of the PhD project is to enhance the sensitivity in mechanical measurements by means of quantum correlations and entanglement. The latter are generated in ultracoherent optomechanical systems [1-3] by means of parametric modulation or stroboscopic probing [4]. Both theoretical modelling and experimental implementation will be part of the project. Applications range from gravitational wave detectors to quantum-limited scanning probe microscopy.

The research is embedded in the Center of Excellence “Hybrid Quantum Networks Hy-Q ,” whose mission is to merge disparate quantum system into large scale quantum networks.

We are looking for individuals enthusiastic to acquire, apply and advance their scientific skills within a dynamic international team. Experience in the fields of experimental and theoretical quantum optomechanics, electromechanics, nanomechanics, and ultralow-temperature techniques is a plus.

Employment date is 1 October  2021 or as soon as possible thereafter.

Principal supervisor isProf. Albert Schliesser, Niels Bohr Institute,

Job description
The PhD position is for a 3-year period and the key tasks as a PhD student at Science are:

  • To manage and carry through your research project 
  • Attend PhD courses
  • Write scientific articles and your PhD thesis
  • Teach and disseminate your research
  • To stay at an external research institution for a few months, preferably abroad
  • Work for the department

Formal requirements
Applicants should have an MSc degree in physics or related fields with excellent results and very good English skills. As criteria for the assessment of your qualifications emphasis will also be laid on previous publications (if any) and relevant work experience.

Terms of employment
The position is covered by the Memorandum on Job Structure for Academic Staff.

Terms of appointment and payment accord to the agreement between the Ministry of Finance and The Danish Confederation of Professional Associations on Academics in the State.

The starting salary is currently at a minimum DKK 328,355 including annual supplement (+ pension up to DKK 53,360). Negotiation for salary supplement is possible.

Application Procedure
The application, in English, must be submitted electronically by clicking APPLY NOW below.

Please include

  • Cover Letter, detailing your motivation and background for applying for the PhD project
  • CV
  • Diploma and transcripts of records (BSc and MSc)
  • Acceptance Letter for the relevant MSc Programme at SCIENCE, if any
  • Other information for consideration, e.g. list of publications (if any),
  • 1-3 reference letters (if any)

Reference letters must be uploaded by the applicant him/herself. The recruiting person must NOT  obtain reference letters which content is not known to the applicant him/herself. This is against Danish law.

The University wishes our staff to reflect the diversity of society and thus welcomes applications from all qualified candidates regardless of personal background.

The deadline for applications is 4 July 2021. 23:59 GMT +2
Applications received later than this date will not be considered.

After the expiry of the deadline for applications, the authorized recruitment manager selects applicants for assessment on the advice of the Interview Committee. Afterwards an assessment committee will be appointed to evaluate the selected applications. The applicants will be notified of the composition of the committee and the final selection of a successful candidate will be made by the Head of Department, based on the recommendations of the assessment committee and the interview committee.

The main criterion for selection will be the research potential of the applicant and the above mentioned skills. The successful candidate will then be requested to formally apply for enrolment as a PhD student at the PhD school of Science.
