PhD Position in Experimental Physics with focus on Optical Frequency Comb Spectroscopy

2 weeks ago


Umeå, Västerbotten, Sweden Umeå University Full time

Department of Physics is seeking a PhD student in experimental physics for a project focused on high-resolution optical frequency comb spectroscopy of molecules relevant in astrophysics. The position will be available in fall 2024 (exact start date negotiable) with an application deadline of Jun 10, 2024.

Project Description
The Optical Frequency Comb Spectroscopy Group is dedicated to the development and application of optical frequency comb spectroscopy for precise measurements and sensitive detection of molecular species in gas phase.

  • We are looking for a PhD student to join a project targeting high-resolution broadband spectroscopy of astrophysically significant molecules.
  • Satellite and ground-based observations of hot-Jupiter exoplanets have detected molecular species in their atmospheres, providing valuable information on composition and conditions. Accurate theoretical models and high-precision laboratory data are crucial for understanding these spectra.
  • Utilizing double-resonance spectroscopy with a frequency comb probe, we aim to selectively measure and assign individual hot-band transitions of methane and other important molecules in astrophysics.
  • The PhD project involves measuring and assigning hot band transitions up to 9000 cm-1 energy levels in ethylene and advancing to 12000 cm-1 energy levels in methane to verify theoretical predictions and enhance modeling accuracy of high-temperature environments in exoplanets.

The project includes system development, data analysis, and collaboration with theorists, offering a dynamic, ambitious, and international environment with opportunities for presenting papers at conferences.

Competence Requirements
Applicants must have completed a second-cycle degree in physics with experience in experimental laboratory research, optics, and electronics. Proficiency in English is a must.

Terms of Employment
The employment aims for a doctoral degree with research project participation, course attendance, and optional teaching/dept. work (up to 20%). The position is limited to four years (full-time) or five years with additional tasks. Salary follows doctoral student standards.
