at the Department of Physics. Closing date: 10 December 2020.

The Department of Physics is located in the AlbaNova University Center and has approximately 240 employees, 250 students at undergraduate level and 95 graduate students. There are four research subjects within the postgraduate program: Physics, Theoretical Physics, Chemical Physics and Medical Radiation Physics. These subjects span over several research groups with different research activities. For information about the Department of Physics, see:

Project description
Subject: Theoretical Physics/Chemical Physics.

Directing molecular movies - Quantum mechanical simulations of time-resolved X-Ray/XUV spectroscopy.

Two PhD openings are immediately available for outstanding individuals to work on the development of theoretical simulations of time-resolved X-Ray/XUV spectroscopy.

Ultrafast X-ray sources open up a range of new possibilities for exploring the internal structure of molecules during chemical reactions, but improved theoretical modelling is required to utilized the potential. The extreme combination of temporal and spectral resolution is not available in conventional optical femtosecond experiments.

Ultrashort laser pulses in the extreme ultraviolet and X-ray laser regime, as they are provided by free electron laser and high harmonic generation sources, allow for resolving the coupled nuclear+electronic dynamics in photochemical processes. Ultrafast hard X-ray sources make time-resolved diffraction experiments possible, paving the way to capture the nuclear dynamics of molecules in time as well as in space, with the "molecular movie" of a chemical reaction as the ultimate goal.

The successful applicant will develop simulation methods for advanced X-Ray/XUV spectroscopic methods, perform quantum chemical calculations, run molecular dynamics simulations, and will work in collaboration with experimental groups.

The training primarily involves theoretical methods, but the project is embedded in a Marie Skłodowska-Curie training network [SMART-X] ( including academic and non-academic partners engaged in both theoretical and experimental activities. The position requires 4 secondments with a total duration of at least 6 months in partner institutions within the network (outside Sweden).

We are looking for self-motivated candidates who are fluent in English and who are enthusiastic about working on theory projects that combine state-of-the-art chemistry, electronic structure calculations, quantum mechanics and physics. Prior training in theoretical chemistry, molecular physics, or quantum optics, and knowledge in computer programming languages is of advantage.

Note that in order to be eligible for the position you must no have more than four years of full time research experience and must not have a doctorcal degree.

Furthermore you must not have resided or carried out your main activity (e.g. work, studies) in Sweden for more than 12 months in the 3 years immediately before the recruitment date.For more detailed information see

The project involves two theoretical groups at the Division of Chemical Physics and more information about the research activities can be found at our respective group pages: and

Education at the research level
A PhD education at Stockholm University is four years (48 months). The 4-year PhD program includes at least 3 years of research and at most one year of course work.

The position may be extended by up to one year if up to 20 % teaching assistance or administration is included in the contract. The PhD student is employed (“doktorandanställning”) during the studies, with a monthly salary starting at SEK 26 500.

Qualification requirements
An applicant who has completed a second-cycle (master's) degree, or completed courses equivalent to at least 240 higher education credits (4 years of studies), of which 60 credits must be in the second cycle, or have otherwise acquired equivalent knowledge in Sweden or elsewhere, meets the general entry requirements.

In order to be accepted as a PhD student in Physics or Theoretical Physics a BSc in Physics (or equivalent) is required. The studies must include 60 credits of second-cycle courses in physics out of which at least 15 credits correspond to a second-cycle degree project. The degree project does not have to have been examined at the application deadline, but work corresponding to half a semester of full-time studies should have been devoted to it. For the subject Chemical Physics courses in chemistry may replace the required physics courses.

The qualification requirements must be met by the deadline for applications.

The selection among the eligible candidates will be based on their capacity to benefit from the training.

The successful applicant will be selected based on documented theoretical and experimental knowledge relevant for the area of study, knowledge of scientific theory and method, analytical skills, personal motivation and team working skills.

Well-developed English language skills are required.

The applicants are encouraged to provide supporting documents that substantiate qualifications, e.g., knowledge, skills, abilities and experience. References and interviews will be used to assess qualifications of the applicants. We seek a self-motivated candidate with good analytical abilities and skilled in English.

Admission Regulations for Doctoral Studies at Stockholm University are available at: and regulations.

Terms of employment
Only a person who will be or has already been admitted to a third-cycle programme may be appointed to a doctoral studentship.

The term of the initial contract may not exceed one year. The employment may be extended for a maximum of two years at a time. However, the total period of employment may not exceed the equivalent of four years of full-time study.

Doctoral students should primarily devote themselves to their own education, but may engage in teaching, research, and administration corresponding to a maximum of 20 % of a full-time position.

Please note that admission decisions cannot be appealed.

Stockholm University strives to be a workplace free from discrimination and with equal opportunities for all.
