The recently-discovered material K2Cr3As3 has a structure consisting of parallel Cr-As chains, which gives an opportunity to study the exotic behaviour which is predicted to occur when electrons are effectively confined to move only in one-dimension. Its peculiar properties, having an unusual metallic state before superconducting at 7 K, have made researchers curious about how best to describe the conduction electrons in the system.
