Abstract

The alkali hyperoxide KO $_2$ is a molecular analog of strongly-correlated systems, comprising of orbitally degenerate magnetic O $_2^-$ ions. Using first-principles electronic structure calculations, we set up an effective spin-orbital model for the low-energy \textit{molecular} orbitals and argue that many anomalous properties of KO $_2$ replicate the status of its orbital system in various temperature regimes.
