Electronic Order in Kagome Metals

Kagome metals have emerged as a platform for correlated and topological physics in itinerant electron systems due to their high degree of orbital frustration. The Dirac cone and flat-band physics of toy models is modified in material realizations that give rise to strongly interacting ground states, such as charge order and superconductivity. Tied to the lattice, these systems promise to realize the long-sought dream of controlling intertwined electronic orders, which both advances our understanding of these materials as well as promises novel applications of quantum materials. With a focus on the AV₃Sb₅ (A = K, Rb, Cs) class of materials, we address the mounting experimental evidence for a thus-far unexplained state that bears characteristics of a chiral state with delocalized orbital anti-ferromagnetism. The contradictory state of experimental evidence points to extreme sensitivity of this state to external perturbations, a point of focus at the workshop. With this highly interactive workshop, we aim for a convergence of a minimal model for the interacting state in such Kagome metals, and to derive a roadmap addressing the current open questions on microscopics, proposing complementary materials platforms and solidifying ideas towards interacting topological electronics.

The conference language will be English. The Wilhelm and Else Heraeus-Foundation bears the cost of full-board accommodation for all participants.
