Correlated states refer to the collective behavior of many particles in a material that are strongly linked or correlated with each other. This can result in unique and interesting physical phenomena, such as superconductivity, magnetism, and exotic phases of matter. Researchers study correlated states in various types of materials, including superconductors, quantum magnets, and topological insulators, to better understand the underlying physics and potentially discover new materials with novel properties. This research area is important for advancing our understanding of condensed matter physics and potentially unlocking new technologies based on these correlated states.
