Postdoctoral fellowship (2 years) in Optical Frequency Comb Spectroscopy

Department of Physics is looking for a postdoctor to join the Optical Frequency Comb Spectroscopy Group and participate in a project aimed at double-resonance spectroscopy of small molecules using an optical frequency comb probe.

Project Description

The Optical Frequency Comb Spectroscopy Group (www.umucombs.org) works with development and applications of optical frequency comb spectroscopy for broadband precision measurements and sensitive detection of molecular species in gas phase. We are now seeking a postdoctor to join the project aimed at double-resonance spectroscopy of small molecules using a frequency comb probe. Following the initial demonstration (Phys. Rev. Lett. 126, 063001, 2021 and Phys. Rev. A 103, 022810, 2021), we are now developing a cavity-enhanced system with increased sensitivity and spectral coverage of the comb probe. The aim of the project is to measure and assign hot band transitions reaching the 9000 cm-1 energy levels in methane, acetylene and ammonia – molecules of astrophysical importance. The project encompasses further development of the detection system, data acquisition and analysis, and theoretical modelling of the signals. Our group offers a dynamic, creative, ambitious and international environment, with many external collaborations and opportunities for the postdoc fellow to present papers at international meetings and conferences.

The project is for two years starting by agreement. The stipend is financed by the Knut and Alice Wallenberg Foundation and it amounts to 372 ooo SEK per year (the stipend is tax-free).

Qualifications

To qualify for the position, the candidate should hold a PhD degree or a foreign degree that is deemed equivalent to a PhD degree in experimental physics or equivalent subject. To be eligible the degree should have been completed a maximum of three years before the end of the application period unless special circumstances exist (these include absence due to illness, parental leave, appointments of trust in trade unions or similar). The ability to develop independently as well as in a team and fluency in written and oral English are essential. The candidate should have previous experience with precision spectroscopy and development of laser-based spectroscopic systems.

Application

The application should include:

  1. A motivation letter describing previous research experience relevant to the project (max 2 pages).
  2. Curriculum vitae with a list of publications.
  3. Copy of the PhD thesis.
  4. Copies of two most relevant publications.
  5. Certified copies of doctoral degree certificate and other relevant exam certificates.
  6. A list of university courses with grades.
  7. Contact information of three reference persons.
  8. Other documents you wish to claim.

Submit your application as a PDF marked with the reference number FS 2.1.6-2250-21, both in the file name and in the subject field of the email, to medel@diarie.umu.se. The application can be written in English (preferably) or Swedish. Application deadline is 14 January 2022.
