PhD fellow in Quantum Electro- and Optomechanics at Niels Bohr Institute. Faculty of Science

The Niels Bohr Institute, Faculty of Science at University of Copenhagen, is offering one or more PhD scholarships in Quantum Electro- and Optomechanics commencing on 1.9.2017 or as soon as possible thereafter. 

We are looking for highly motivated, excellent candidates with a master’s degree in physics or related fields. Knowledge and experience in any of the relevant fields described below is a plus, but not a necessity. Enthusiasm to acquire, apply and advance scientific skills within a dynamic, hard-working and international team is key. 

Project description In this project you will probe the motion of mechanical resonators membranes with sub-micron to millimetre dimensions in the quantum regime. The experiments can build on one of the world’s most advanced optomechanical platforms, providing mesoscopic mechanical resonators with coherence times previously reserved to isolated atomic systems (arXiv:1605.06541 and arXiv:1608.00937). 

Coupling them to microwave and optical resonators allows displacement measurements not only at the attometer level, but in a regime where quantum fluctuations are central to the motional dynamics. This will enable us to realise non-classical states of motion, photon-phonon conversion and entanglement. We will harness these opportunities to test new quantum measurement protocols for mechanical displacements relevant e.g. for gravitational wave interferometers such as LIGO but also microwave or optical fields, with potential applications as building blocks in hybrid quantum systems for sensors and networks. 

The research involves design and fabrication of nanomechanical hybrid devices, quantum optical and microwave measurement techniques, measurements at low and ultralow cryogenic temperatures, numerical simulations using finite-element methods, and quantum-mechanical modelling of the system. The research is embedded in several international collaboration networks. Principal supervisor is Prof. Albert Schliesser, Niels Bohr Institute, albert.schliesser@nbi.dk 

Formal requirements The position is available for a 3-year period for applicants holding a relevant master’s degree.

Job Description The position is available for a 3-year period and your 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
  • Work for the department

 Applicants who are already enrolled or are accepted to be enrolled at one of the Faculty’s master’s programs can hold the position for a 4-year period. Applicants for the 4-year period must have, at the time of commencement, approximately one year of study remaining before graduating from their MSc programme. 

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.

Application Procedure The application, in English, must be submitted electronically by clicking APPLY NOW below.
Please include the following material in your application:

  • Cover Letter, describing your motivation and relevant experience
  • Curriculum Vitae
  • Diploma and transcripts of records (BSc and MSc)
  • Other information for consideration, e.g. list of publications (if any)
  • Contact details (Name, telephone & email) of 1-3 references
  • Finalists will need to provide documentation of English language proficiency

The applicant will be assessed according to the Ministry of Science Technology and Innovation Executive Order no. 1039 of 27 August 2013 PhD Order.

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 30.6.2017. Applications received later than this date will not be considered. 

More Information For further information on the study structures, please see: www.science.ku.dk/phd. General information about PhD programmes at SCIENCE is available in the Faculty PhD Rules.

For specific information about the PhD scholarship, please inquire with the principal supervisor. Further information about the research can be found at http://slab.nbi.dk/
