Outline of Final Research Achievements

In this research project, we explored the interplay between correlations and topology in Kondo insulators and Weyl semimetals with the ultimate goal of uncovering novel and unique phenomena. We showed how correlations, magnetism, and non-Hermiticity affect the symmetry-protected surface states in these systems. An important part of our research was the analysis of quantum oscillations in magnetic fields in topological Kondo insulators. We found a theoretical explanation of these quantum oscillations based on correlations and spin-orbit interaction. Furthermore, we demonstrated that correlations lead to a giant enhancement of nonlinear responses, exemplified by a large nonlinear Hall effect in a Weyl-Kondo semimetal. Our research on the interplay between correlations and nontrivial topology in Kondo insulators and Weyl semimetals has uncovered novel and unique phenomena that shed light on the complex interactions between magnetism, correlations, and non-Hermiticity in these systems.

Academic Significance and Societal Importance of the Research Achievements

Topological nontrivial, interacting materials are an exciting class of materials with potential applications in fields such as quantum computing and energy storage. During this research project, we advanced our knowledge about the interplay of topology and strong correlations in these materials.
