Topology in relativistic semimetals (TOPREL)
Final Report Abstract
The project „Topology in relativistic semimetals (TOPREL)” was concerned with exploring electronic properties in relativistic topological materials. Its goal was to more tightly connect relativistic concepts such as an emergent space-time metric and black holes, and relativistic dispersion relations, to properties of electrons in actual materials. The project had four main research lines (RLs). • RL1 was about analyzing the impact of tilted Weyl nodes on transport. • RL2 dealt with calculating thermoelectric transport properties in relativistic materials from first principles. • RL3 analyzed dissipative topology in relativistic materials, for example in open setting. • RL4 focussed on hydrodynamic transport in quantum materials. Overall, the project has made important progress in almost all research directions. RL1, which was under my guidance, lead to a rather complete analysis of how tilted nodes affect transport. In summary, the project TOPREL has lead to many intriguing insights into how relativistic physics can shape electronic properties in quantum materials. To cite just one highlight, it proposed tilttonics as a future avenue for applications such as electronic lensing. It also deepens the collaboration between my group and the group of Prof. Schmidt, and has successfully strengthened the research connections between Germany and Luxembourg in the field of condensed-matter physics.
