Lund University was founded in 1666 and is repeatedly ranked as one of the world's leading universities. Here, approximately 46,000 students and 8,500 employees work in Lund, Helsingborg, and Malmö. We are united in our endeavor to understand, explain, and improve our world and people's conditions.
Description of the Operation
The Department of Synchrotron Radiation Physics (http://www.sljus.lu.se) is part of the Physics Institute and has more than 50 employees. The research focus is on experimental studies of electronic, structural, and chemical properties of materials. The department develops activities in magnetic properties. At the department, we use and develop a wide range of synchrotron, neutron, and lab-based techniques. We are also involved in developing beamlines, experimental stations, experimental techniques, and accelerator systems for the MAX IV laboratory, and we maintain close ties with the European Spallation Source (https://www.ess.eu), a new European neutron facility under construction adjacent to MAX IV. MAX IV is a national large-scale laboratory that is part of Lund University and is located within cycling distance of the Physics Institute.
A significant part of this project will be conducted at the Institut Laue-Langevin in Grenoble, France, which is Europe's leading research facility for science using neutrons. Every year, ILL receives over 2,000 visits from researchers using a state-of-the-art set of neutron scattering instruments for research in various fields, and particularly in fundamental materials science and condensed matter.
More specifically, and most relevant for this project, neutron spectroscopy is used to investigate materials dynamics, which is key to understanding quantum mechanical phenomena.
Being a PhD Student
As a doctoral student, you are both admitted as a student and employed at Lund University.
As a research student, you are trained in a scientific approach. This can briefly be described as gaining practice in critical and analytical thinking, solving problems independently with the right choice of methods, and developing research ethics awareness. Additionally, as a doctoral student, you have the opportunity to work on projects, develop your leadership skills, and enhance your pedagogical abilities. Throughout your studies, you are guided by supervisors. Doctoral studies conclude with a dissertation and a doctoral degree.

Subject and Project Description
Electron interactions in materials constitute a rich and complex source of physical problems, partly due to the challenges in handling the large number of many-body interactions. These interactions give rise to fundamental quantum mechanical states such as superconductivity and magnetism. New quantum states of matter are discovered regularly. External perturbations can drive a magnetic state into a new phase, which provides important information about the internal exchange interactions.
The main research focus of this position is to investigate how heat transport in crystals can be affected by a magnetic field. This is observed in the thermal Hall effect, which is the thermal counterpart to the Hall effect. In many materials, an orthogonal heat gradient arises when a heat gradient is applied and a magnetic field is subsequently applied. The mechanisms behind this are still unknown. In this project, this will be investigated with a focus on thermal carriers, using inelastic neutron scattering to identify and characterize potential carriers, with the aim of explaining how they couple to an external magnetic field. With this information, we will be able to test theoretical explanations and clarify what types of mechanisms are possible in such quantum materials.
The project will involve experimental work at large-scale facilities (synchrotron and neutron sources) around the world. Data analysis of the XPCS method will require handling large datasets.
General Study Plan for Doctoral Education
Work Tasks
You will primarily dedicate yourself to your doctoral studies, which largely consist of writing a doctoral dissertation. You will conduct experimental work at large-scale facilities (synchrotron and neutron sources) around the world, primarily in Europe, complemented by laboratory experiments at Lund University. You will present your results at seminars and conferences. The experimental work includes preparing samples, setting up experimental equipment, and collecting data. You will also participate in the design and fabrication of a sample holder that enables heat transfer measurements, in collaboration with experts. For work at large-scale facilities, experimental time is allocated through competitive peer review, and you will learn to write successful applications. You will also work on analyzing experimental data and comparing it with theoretical models. As part of your doctoral education, you will also take certain courses, both in your subject area and in transferable skills. Beyond studies, a maximum of 20% of working time may be devoted to teaching and other institutional work.
