PhD position in theoretical physics

The Junior Research Group "Decoherence in gravitating and gravity-exposed quantum systems" at the Theoretical Physics Institute, Faculty of Physics and Astronomy at Friedrich-Schiller University Jena, Germany invites applications for a

PhD position in theoretical physics

starting mid 2020 (flexible start date).

The Junior Research Group led by Dr André Großardt studies effects of gravitational decoherence in laboratory quantum systems comparing quantised and classical gravitation, possible ways of coupling quantum matter to classical gravity, as well as the relevance of gravitational decoherence effects for the measurement problem in quantum mechanics.

Your tasks:

  • Analysis of existing models of stochastic background spacetimes and of quantum and classical sources of such perturbations.

  • Comparison of existing models for decoherence due to stochastic spacetime perturbations.

  • Independent research on the extension and generalisation of these models for comparability of classical and quantum effects.

Qualification requirements:

  • University degree in Physics or comparable degree.

  • Interest in foundational question of theoretical physics and ability for critical consideration of established explanatory models.

  • Preferably experience (e.g. Master’s thesis, focus/elective subject) in gravitational physics or foundations of quantum mechanics (decoherence, open quantum systems, …) ideally with elementary knowledge in the respective other area.


We offer:

  • A challenging research project with the opportunity to determine your own research focus.

  • A family friendly employment environment with flexible work hours.

  • Salary and benefits according to the salary scheme for state employees (TV-L) in salary group E13 (75%).

The contract will be fixed-term for 3 years with 30 working hours weekly (75% of full-time position).

Severely disabled people are given preference, equal capabilities, aptitude, and professional qualification provided.

A complete application (in English or German) includes

  • CV,

  • Transcript of grades,

  • Short (1 page) English language summary of your Master’s and/or Bachelor’s thesis,

  • Short presentation of your scientific motivation in 1-2 pages: what do you think are the most important foundational questions in physics, where do you see promising approaches for their solution, and where do you see your personal role in this?

  • Contact information for 2 references (name, institution, email). These persons should be willing and able to judge your scientific qualification upon request (note that no letters of reference should be sent at the time of application!)

Please send in your application by the end of 15 March 2020 addressed to

Dr André Großardt
