PhD project on an undulator light source for design and control of novel materials
Uppsala University is an international research university focused on the development of science and education. Our most important assets are all the individuals who with their curiosity and their dedication make Uppsala University one of Sweden’s most exciting work places. Uppsala University has 40,000 students, 7,000 employees and a turnover of SEK 6,5 billion.
The Department of Physics and Astronomy is the second largest at Uppsala University with more than 360 employees and 11 different divisions and is situated at Ångström Laboratory in Uppsala.
The candidate is offered the possibility to work in an exciting modern research area in physics and will have opportunities to interact and collaborate with leading experimental and theoretical groups. Prospective applicants are expected to be strongly motivated. Excellent capabilities to perform research should be demonstrated through an excellent transcript of records.
Description of Subject Area:
Macroscopic properties of solids are determined by underlying fundamental characteristics of their spin, phonon and electron subsystems as well as interactions between the subsystems. Coherent excitation by a light pulse of the subsystem of a solid allows tailoring of its macroscopic properties. This enables the creation of materials with new dynamic functionalities such as, for example, THz light induced superconductivity, ps scale switching on and off of magnons, and stimulated ns oscillations between a metallic and an insulating state. To fully exploit the potential of the coherent control of these subsystems, appropriate sources of light are needed.
The challenge of this PhD project is twofold: to develop methods of the generation of single-cycle light and light carrying orbital momentum with undulators, and study the interplay between the phonon oscillations and magnetization dynamics in a nanomagnetic array excited by a pulse of light. During the first year of the PhD study, a successful candidate will mainly work on the light-matter interaction in the mentioned array composed of nanoscale magnetic inclusions to understand how the magnetic properties of materials can be tailored with light. In particular, together with the colleagues the candidate will address the coupling between the magnetization dynamics of the nanoscale magnetic inclusions in the presence of a phonon excitation of the whole array. During the next years, the focus of the PhD project will be on novel light sources based on undulators. Undulators are a key component of coherent light sources such as synchrotrons and free-electron lasers, and have traditionally been used to generate multicycle wavefronts. The challenge of the project is to develop a method for generation as short pulses as just one cycle using undulators. The project comprises analytical calculations, numerical simulations, planning and participation in a proof-of-principle experiment.
