"capable of forming correlated states—"electron soups" that can host a variety of quantum phases, including superconductivity... Unlike in any other superconductor we know about, CDWs appear even before we dope the material by replacing some atoms with others to change the number of electrons that are free to move around nickelate host both CDWs and superconducting matter... doping essential part of getting materials to superconduct"
