Abstract: Interactions between localised spins and mobile fermions underlie the transport properties of many strongly correlated materials. Even a single localised spin impurity can dramatically affect the motion of a great number of fermions in its vicinity, giving rise to a remarkable phenomenon in quantum many-body physics – the Kondo effect. For a finite density of localised spins, the Kondo effect further competes with fermion-mediated long-range spin interactions. The EU-funded OrbiDynaMIQs project will probe the elementary dynamical and spatial properties of the Kondo effect. It will develop a novel, rapid quantum simulator based on ultracold fermionic ytterbium atoms, and will focus on the spin-orbital dynamics of single and multiple impurities embedded in 1D and 2D itinerant fermion systems.
