quantum material cerium-rhodium-arsenic (IMAGE) Technische Universität Dresden Caption The figure shows the exceptionally robust quantum material cerium-rhodium-arsenic (CeRh2As2), which Elena Hassinger is researching at the Cluster of Excellence ct.qmat. Cooper pairs (yellow) are located near the cerium atoms (blue). These are formed at very low temperatures from two electrons each and are a prerequisite for superconductivity. Collectively, they can form a quantum state and move through the superconductor without resistance.
