Lund University, Faculty of Engineering, LTH, Department of Physics

Lund University was founded in 1666 and is repeatedly ranked among the world’s top 100 universities. The University has around 44 000 students and more than 8 000 staff based in Lund, Helsingborg and Malmö. We are united in our efforts to understand, explain and improve our world and the human condition.

LTH forms the Faculty of Engineering at Lund University, with approximately 9 000 students. The research carried out at LTH is of a high international standard and we are continuously developing our teaching methods and adapting our courses to current needs.

The Department of Physics is with a staff of about 350 scientists and educators one of the largest departments within Lund University. There are seven research divisions and a number of research centra within the department. The research activities at the department cover a broad spectrum of modern physics.

The Unit for Combustion Physics conducts extensive operations with emphasis on the development of laser spectroscopic techniques for both basic studies and applications in, among other things. combustion processes, gasification, catalysis, nanometer fabrication and plasma production. In recent years, the unit has also established significant research activities in the field of biophotonics. Within the unit's operations, there are extensive national and international collaborations with both academia and industrial partners. The Department of Combustion Physics has since 2001 been located in the new and modern building called Enoch Thulin laboratory at the Department of Physics where currently about 60 people work at the unit.

Work duties

The main duties of doctoral students are to devote themselves to their research studies which includes participating in research projects and third cycle courses. The work duties also include teaching and other departmental duties (no more than 20%).

Optical and laser-based measurement methods are many times ideal for non-invasive investigations of complicated and difficult-to-access processes without affecting and adversely affecting the measurement object. This project focuses on engines powered by renewable hydrogen. Such engines have the potential to combine high energy efficiency and climate neutrality. Besides reducing the future great need for batteries in the transport sector, these engines can become especially important for reaching the climate targets of long-range, heavy transports that are difficult to electrify.

The research work will concern development and application of laser-based measurement methods to study the in-cylinder processes in engines fuelled by renewable hydrogen. The research activities connect to related processes in industry such as heat and power generation, propulsion, etc.  The measurement techniques that will be applied involve the handling of advanced technical equipment, such as powerful pulsed lasers and high-speed detectors. Image processing will be of central importance for the evaluation work. Once the methods have been commissioned and verified, they will be used in applied studies, in engines with optical access, to investigate the extremely fast processes involved.  

The work will be focused on experimental research that in the applications will be combined with technical challenges for high voltage discharges, plasma and spectroscopy. The diagnostic development part includes both programming and handling of advanced experimental equipment, which requires theoretical and practical knowledge in mathematics, physics and chemistry. The experimental work will to a significant extent be shaped by the doctoral candidate. The target is to understand the wear mechanism in detail and for this purpose several tools are available, such as high-speed photography, laser excitation, spectrally resolved detection, etc. The project is performed in close collaboration with the industrial partners, SEM AB, Scania CV AB and Volvo AB.

Admission requirements

A person meets the general admission requirements for third-cycle courses and study programmes if he or she:

  • has been awarded a second-cycle qualification, or
  • has satisfied the requirements for courses comprising at least 240 credits of which at least 60 credits were awarded in the second cycle, or
  • has acquired substantially equivalent knowledge in some other way in Sweden or abroad.

A person meets the specific admission requirements for third-cycle studies in Physics if he or she has:

  • at least 30 second-cycle credits of relevance to the subject, of which at least 15 credits shall comprise a second-cycle degree project, or
  • an MSc in engineering physics or an associated field, or a Master’s degree in physics or an associated field.

Additional requirements:

  • Very good knowledge of English, in speech and writing, is a requirement.
  • Good theoretical and experimental knowledge in the fields of optics, laser and spectroscopy.
  • Good knowledge of MATLAB or similar program languages.

Finally, the student must be judged to have the potential to complete the programme

Basis of assessment

Selection to postgraduate studies is based on the expected ability to perform well in the studies. The evaluation of the ability to perform well is based primarily on the results of studies at the basic and advanced levels, in particular:

  1. Knowledge and skills relevant to the thesis project and the subject of the study.
  2. An assessment of ability to work independently and to formulate and tackle research problems. This assessment could for example be made from the master’s project or a discussion about this project in an interview situation.
  3. Written and oral communication skills
  4. Other experience relevant to postgraduate studies, such as professional experience.

Other assessment criteria

  • Experience in experimental laser diagnostics.
  • Experience in analysing experimental data.
  • Experience in Labview or similar program languages for controlling experimental equipment.

Consideration will also be given to good collaborative skills, drive and independence, and how the applicant, through his or her experience and skills, is deemed to have the abilities necessary for successfully completing the third cycle programme.

Terms of employment

Only those admitted to third cycle studies may be appointed to a doctoral studentship. Third cycle studies at LTH consist of full-time studies for 4 years. A doctoral studentship is a fixed-term employment of a maximum of 5 years (including 20% departmental duties). Doctoral studentships are regulated in the Higher Education Ordinance (1993:100), chapter 5, 1-7 §§.
