Topologically-protected conductors of information are robust against perturbations that would normally scatter the information carriers, resulting in waste heat and reduction of energy efficiency. In addition to topological protection of electronic charge transport, such protection of propagating fluctuations of the magnetization – dubbed spin waves or magnons – has recently been gaining attention. This PhD project will focus on understanding, modelling, and controlling these topologically-protected spin waves, addressing both fundamental questions and potential applications.

Your job

This project consists of a theory-experiment collaboration in which a PhD candidate in Condensed-Matter Theory based at Utrecht University, supervised by Prof. Rembert Duine, collaborates closely with a PhD candidate in Experimental Nanomagnetism, supervised by Prof. Bert Koopmans, based at Eindhoven University of Technology. 
In this project, we aim to develop an optical pen using laser-induced magnetization dynamics and switching to write topological magnetic periodic structures that consist for example of skyrmions, topological magnetic whirls in the magnetization. Along the edges of such structures, a topologically-protected fluctuation of the magnetization will propagate without scattering and loss of energy. Such structures could potentially be a novel building block for future computer chips and more sustainable IT technologies.
Your research will be to develop the theory for the dynamics of laser-induced creation of magnetic skyrmions and other magnetic structures. You will also create the theoretical description of magnetic excitations on top of such structures. In doing so, you will develop both analytical theory and perform numerical simulations. 
You will collaborate closely with your experimental partner in Eindhoven, exploring opportunities and open questions that arise from the experiments, as well as suggesting new directions for the experiments to explore. You will publish your findings in research articles and by giving talks and presenting posters at national and international research conferences. During the four-year period of the PhD position, you will grow into an independent researcher who can conduct research in a collaborative environment. 

Your qualities

We are looking for a collaborative and driven candidate who:

• holds a Master’s Degree in Physics, with a specialization in theoretical physics;
• is enthusiastic about fundamental condensed-matter physics, as well as its connection to experiments and applications;
• has strong English skills, both in speaking and in writing.

Our offer

• a position for 18 months, with an extension to a total of four years upon a positive assessment in the first 18 months;
• a permanent employment contract;
• a full-time working week and a gross monthly salary between € 3.059 and €3.881 in the case of full-time employment (salary scale P under the Collective Labour Agreement for Dutch Universities (CAO NU));
• 8% holiday pay and 8.3% year-end bonus;
• a pension scheme, partially paid parental leave and flexible terms of employment based on the CAO NU.

In addition to the terms of employment laid down in the CAO NU, Utrecht University also offers a range of its own schemes for employees. This includes arrangements for professional development, various types of leave, and options for sports and cultural activities. You can also tailor your employment conditions through our Terms of Employment Options Model. In this way, we encourage you to keep investing in your personal and professional development.

About us

A better future for everyone. This ambition motivates our scientists in executing their leading research and inspiring teaching. At Utrecht University, the various disciplines collaborate intensively towards major strategic themes. Our focus is on Dynamics of Youth, Institutions for Open Societies, Life Sciences and Pathways to Sustainability. Sharing science, shaping tomorrow.

Working at the Faculty of Science
You will be part of the group of Prof. Rembert Duine at the Institute for Theoretical Physics at Utrecht University. The group’s primary research focus is on the non-equilibrium dynamics of nanoscale systems, with an emphasis on spintronics and magnetic materials. Within the institute, you will engage in group activities, such as common group meetings, to explore new research directions. You will also contribute to teaching of problem classes, and be given the opportunity to explore your own ideas through the supervision of MSc and BSc students. 
Nationally, you will become a member of the Dutch Research School of Theoretical Physics and engage in its activities across the Netherlands.
