PhD Scholarship in Simulating Advanced Ultrafast Time-resolved X-ray Spectroscopy Methods

Outstanding international students are invited to apply for a PhD scholarship in optics at Stockholm University. The funding allows successful candidate to work for 4 years. Applications are invited up to March 03, 2019.

The Department of Physics is located in the AlbaNova University Center and has approximately 240 employees, 250 students at undergraduate level and 90 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: www.fysik.su.se/english.

Conical intersections (CoIns) provide ultra fast, radiation-less decay channels in poly-atomic molecules. They play a crucial role in many photo-chemical and photo-biological processes. The Born-Oppenheimer approximation breaks down in their vicinity and the electronic motion and the nuclear motion become strongly coupled. These CoIns so far have eluded direct experimental observations. The evidence for their existence is based on ultra fast relaxation rates and other indirect signatures. The rapidly varying energy gap in the vicinity of a CoIn poses a main obstacle for their direct detection. The required extreme combination of temporal and spectral resolution is not available in conventional optical femtosecond experiments. Recent technical developments in the domain of free electron laser and high harmonic generation sources made ultra short laser pulses in the extreme ultraviolet and X-ray laser regime possible. This requires support from theory to describe coupled nuclear+electronic dynamics in the vicinity of CoIns under the influence of those laser pulses.

In this project we will theoretically investigate novel experimental techniques for the spectroscopic detection of CoIns with ultra short X-ray pulses. Simulation strategies for non-linear X-ray spectra and diffraction schemes will be developed by the candidate and applied to molecular systems.

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 ("doktorandanstllning") 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 include60 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.

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

Selection

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:www.su.se/rules and regulations.

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.
