PhD Student in Physics: Experimental Attosee Studies of Processes in Small Quantum Systems

Lund University

Sweden

 

Lund University was founded in 1666 and ranks repeatedly as one of the world's top 100 universities. There are 40,000 students and 7,600 employees in Lund, Helsingborg and Malmö. We are united in our quest to understand, explain and improve our world and people's conditions.

At the Faculty of Science, research and education is conducted within biology, astronomy, physics, geosciences, chemistry, mathematics and environmental science. The business is run at nine institutions gathered within the northern university area. The faculty has approximately 1,500 students, 330 graduate students and 700 employees. 

The Department of Physics is one of Lund University's largest institutions with approximately 350 employees. At the department there are seven research departments and a number of major centers. The research at the department covers a wide range of modern physics.

The Department of Synchrotron Light Physics ( www.sljus.lu.se ) has in recent years been the fastest growing part of the physical department, with currently more than 40 employees. The focus of the research is on experimental studies of electronic, structural and chemical properties of materials, especially on surfaces and interfaces or free molecules and clusters. At the department, we use and develop a wide range of synchrotron-based techniques, such as X-ray photoelectron spectroscopy / imaging and X-ray diffraction / imaging. Much of this work is done at the national MAX IV laboratory ( www.maxiv.lu.se/) in Lund, which provides the world-leading synchrotron light source MAX IV with research instruments for researchers from Sweden and the rest of the world. We also have Sweden's largest plant for fungal microscopy.

The Lund Attosecond Science Center (LASC, http://www.atomic.physics.lu.se/lasc ) is a world-leading research center in the field of attositic science and involves more than 20 researchers from different disciplines who work with ultra-fast science and attose customer technology. LASC is today Sweden's largest research environment for studies of ultra-fast dynamics in matter, and belongs to Lund's Laser Center (LLC) which is connected to Laserlab Sweden and Laserlab-Europe. At the LASC there are state-of-the-art attenuation light sources with intense XUV pulses (~ μJ pulse energy at 10 Hz), tunable XUV pulses (at 1 kHz) or ultra short pulses at high repetition rates (200 kHz), which allow study electron movements in atoms, molecules and nanosystems.

The MAX IV laboratory ( www.maxiv.lu.se ) is a national research facility that provides the world-leading synchrotron light source MAX IV with research instruments for researchers from Sweden and the rest of the world. Here, research is conducted on, among other things, small quantum systems.


Duties

The purpose of the project is to investigate the ultra-fast dynamics of processes in small quantum systems, such as atoms, molecules or clusters, with the aid of advanced three-dimensional motion-mapping electron and ion spectrometers. One particular focus is on photoionization processes in multi-electron atoms, with the aim of increasing our understanding of electron correlation and quantum mechanical properties of correlated fermions. In the project, the doctoral student will work with experiments and develop methods for studying ultra-fast processes beyond simple photoionization with attose-second light sources and to some extent free electron lasers. Specific topics for the project include:

  • Studies of ultra-fast dynamics with attose second pulses in atoms or more complex quantum systems,
  • Examination of the interaction of two electrons in a laser field,
  • Development of experimental measurement techniques that are sensitive to specific spin states.

The research group also has access to three fully functioning motion picture-depicting electron and ion spectrometers, two of which are available in advanced light sources such as the LASC and MAX IV laboratory. Basic work will be done in collaboration with LASC. In addition, the experiments can be carried out at free electron lasers or internally in our laboratory at the Physical Department to develop and test new techniques before the experiments are performed with attose-second light sources.

The doctoral student service belongs to the project "Chronoscopy of electron wave packages for studies of intertwined quantum states and the time order in quantum processes", which is a collaboration between the universities in Lund, Gothenburg and Stockholm. The work will be carried out in collaboration with several other researchers at the Department of Physics. There are good opportunities for collaboration with theoretical groups at the Department of Mathematical Physics at the Department of Physics.

The main task is to engage in one's own postgraduate education, which includes participation in research projects and successful participation in postgraduate courses. Participation in graduate schools (eg in ultra-fast science) is possible.


Competence

Basic eligibility for postgraduate education has it as:

  • graduated at advanced level,
  • or completed course requirements of at least 240 higher education credits, of which at least 60 higher education credits at advanced level, with content that is relevant for postgraduate education (eg master's degree in engineering or physics),
  • or, in some other way, within or outside the country, acquired substantially equivalent knowledge.

The requirements for special eligibility for the postgraduate subject matter physics meet the one who has:

  1. at least 30 higher education credits with relevance to the subject area, of which at least 15 higher education credits at advanced level and a specialization of at least 15 higher education credits at advanced level with relevance to the subject area,
  2. or MSc in engineering physics or related subject area,
  3. or master's degree in physics or related subject area.

Finally, the student is required to have the ability needed to take advantage of the education.

Other requirements:

Good knowledge of English, in speech and writing, is a requirement. 


Basis of Assessment

Selection for postgraduate education takes place according to the assessed ability to assimilate the same. The assessment of the ability is mainly based on the study results at the basic and advanced levels. In particular, the following are taken into account:

  1. Knowledge and skills relevant to the thesis work and the educational topic, see Tasks. These can be displayed through attached documents.
  2. Assessed ability for independent work and ability to formulate and attack scientific problems. The assessment can take place, for example, on the basis of the degree project and a discussion about this in the event of an interview.
  3. Ability to write and oral communication.
  4. Other experiences relevant to the education at doctoral level, eg professional experience. programming ability or knowledge in electronics.

Other assessment grounds / qualifications:

Consideration will also be given to good co-operation, forward-thinking and independence, as well as creativity and curiosity. Experience of scientific collaboration with researchers from other disciplines and from other countries is important.

For this employment experience in attosekund or ultra-fast science is a merit. Laboratory skill is important, including the use of imaging electron spectrometers, mass spectrometers and (ultra) high vacuum technology. Experiences of working on second-party light sources and / or with lasers are an additional advantage.


Terms

A doctoral student service is an employment with the main task of devoting himself to his / her own doctoral education according to the study plan. The PhD program has a duration of 4 years for full-time studies. In addition, the holder may be required to fulfill service relating to education, research and technical / administrative work corresponding to a maximum of 20% of full-time. The doctoral student service is then extended to a corresponding degree, but at the most to correspond to 5 years of full-time employment. The doctoral student service is surrounded by special regulations that can be found in the Higher Education Ordinance (SFS 1993: 100, chapter 5, with amendments). As the holder, only one who is admitted to postgraduate education may be appointed.


APPLICATION PROCEDURE

Apply online! The application must contain a letter in which the applicant card describes itself and its research interests. The application must also contain a CV, a copy of the thesis or equivalent or a summary in case the work is not completed, a list of at least two references with contact information, copies of grades and other documents that the applicant wishes to rely on.
