The Gordon and Betty Moore Foundation has awarded grants to support twenty U.S. scientists as experimental investigators in the Emergent Phenomena in Quantum Systems (EPiQS) Initiative. Each investigator will receive $1.6 million of unrestricted support over the next five years to pursue innovative, risky research with a potential for significant advances in the concepts and methods used to investigate quantum materials. The collective impact of these investigators will produce a more comprehensive understanding of the fundamental organizing principles of complex quantum matter in solids
