Description:

Topological semimetals are one of the most rapidly developing areas of modern condensed matter physics. Owing to their topologically non-trivial electronic structure, topological semimetals demonstrate a range of intriguing physical properties, including unusual electronic transport properties. These properties are important not only from the perspective of fundamental physics, but also due to the large application potential of these materials, including in spintronics, quantum technologies, and technologies related to the generation of green energy from waste heat.

Despite intensive research, many of the mechanisms responsible for the exceptional transport properties of topological semimetals remain poorly understood. The aim of the PhD project will be to experimentally investigate and identify the mechanisms underlying anomalous electronic transport in topological semimetals, with particular emphasis on magneto-thermoelectric effects. The research will include measurements of electrical resistivity, the Hall effect, magnetoresistance, and thermoelectric effects (Seebeck and Nernst effects) over a broad range of temperatures and magnetic fields. An important part of the project will also involve the study of quantum oscillations, enabling the experimental determination of the shape of the Fermi surface and the electronic transport parameters of the investigated materials. The research will focus both on well-established topological semimetals and on new materials with potentially topologically non-trivial electronic structures. Addressing the scientific problem posed in the project will contribute to a better understanding of the physics of topological materials and may help identify pathways for designing new materials with tailored functional properties.

The PhD project is well suited for candidates interested in experimental condensed matter physics, quantum materials, and electronic transport. The project will provide an opportunity to gain experience in modern experimental techniques, as well as develop specialized knowledge and expertise in the physics of topological materials. The results obtained during the project will be published in renowned scientific journals and presented at prestigious international scientific conferences.
