Lund University was founded in 1666 and is repeatedly ranked among the world’s top universities. The University has around 47 000 students and more than 8 800 staff based in Lund, Helsingborg and Malmö. We are united in our efforts to understand, explain and improve our world and the human condition.
Lund University welcomes applicants with diverse backgrounds and experiences. We regard gender equality and diversity as a strength and an asset.
Mathematical Physics is a common division between the Natural Science and Engineering (LTH) faculties and is part of the Department of Physics. Research is conducted primarily in the field of quantum mechanical many particle physics, which includes theoretical nuclear structure physics, nanometer physics, quantum information, atomic theory and material modeling, with numerous partnerships both internationally and within Lund University.
Work duties
The PhD students shall work on the development of methods for studies of non-linear interaction and photoionization of atoms by electromagnetic fields. The studies will include laser-driven electron dynamics within atoms into time-dependent excited states, as well as studies of how excited atoms interact on the mesoscopic and macroscopic length scale. Both semi-classical and quantum mechanical description of light will be considered. According to published studies, these excited atoms can be used as a new kind of ”clock” to perform time-frequency analysis of attosecond pulses, but exactly how accurate these measurements can be is still an open question. Atoms are composed of many electrons and their dynamics must, therefore, be approximated in some way. We use the Time-Dependent Configuration-Interaction Singles (TDCIS) method, and diagrammatic many-body perturbation theory, as our starting points. Numerical implementations of new programs and sub-routines will be written in modern FORTRAN. Collaboration on codes within the research group is carried out using GIT. Specific sub-topics for the project include:
A) Development and implementation of a method for mesoscopic and macroscopic effects in the interaction between attosecond pulses and excited atoms. Specific focus toward ultra-fast optics and quantum optics.
B) Development and implementation of a method for time-dependent single excitations that include relativistic effects starting from the Dirac Hartree-Fock equations (RTDCIS). Specific focus toward relativistic attosecond physics.
These PhD positions are part of a project entitled ”Ultra-fast superradiant and subradiant effects from atoms with electrons in superposition”, which is financed by the Knut and Alice Wallenberg foundation (KAW) as a Wallenberg Academy Fellow Grant. The project allows for rapid expansion of the research activities in theoretical attosecond physics at the Mathematical Physics Division at Lund University. There are good opportunities for collaboration with experimental groups at the Atomic Physics Division (such as Prof. Anne L’Huillier in attosecond physics and Prof. Stefan Kröll in quantum optics) as well as theoretical atomic physics at Stockholm University (Prof. Eva Lindroth).
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 can also include teaching and other departmental duties (no more than 20%).
Admission requirements
A person meets the general admission requirements for third-cycle courses and study programmes if he or she:
A person meets the specific admission requirements for third-cycle studies in Physics if he or she has:
Additional requirements:
Assessment criteria
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:
Other assessment criteria
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 §§.
We intend to employ 1-2 PhD students.
