Program Description
In quantum materials, electrons may appear to be simultaneously in motion and stopped. An extensive body of experimental and theoretical work has demonstrated that the exotic and frequently functional properties of quantum materials exactly arise thanks to this electronic dichotomy. Unravelling the duality of electrons is therefore crucial to understand quantum matter states and exploit their full potential for future applications; yet, relevant models are notoriously difficult to calculate and validate for real materials. Here we address this challenge for the iconic Kondo lattice model (KLM), which describes the coherent entanglement of localized electrons leading to magnetic moments with itinerant conduction electrons in strongly correlated metals. Exploiting the spectroscopic power of XAS, ARPES, and RIXS [1], as well as neutron spectroscopy [2], we demonstrate that state-of-the-art electronic structure calculations may now calculate salient properties for real KLM materials quantitatively.
