Abstract: The two-dimensional Kagome lattice comprised of corner-shared triangles is theoretically expected to host multiple exotic band features such as Dirac points, van Hove singularity and flat bands in its tight-binding model. The intricate interplay of these band features w spin-orbit coupling and electron-electron interactions renders the kagome lattice an exceptionally promising platform for the realization of topological and correlated electronic states. Recently, a growing family of transition metal-based intermetallic materials, known as "kagome metals," has been found to faithfully realize the anticipated model kagome electronic structure. In this talk, we will focus on the ongoing advancements in the pursuit of topological and correlated phases in binary kagome metals; in particular, we will highlight the band topology in the ferromagnetic phase, the emergence of flat bands as well as non-Fermi liquid behavior in these kagome metals.
