Universal scaling laws for correlated decay of many-body quantum systems

Abstract Quantum systems are inevitably open, continually exchanging energy and information with the surrounding environment. This interaction leads to decoherence and decay of quantum states. In complex systems, formed by many particles, decay can become correlated and enhanced....

Cooperative and collective quantum light emission from perovskite superball superstructures

Superfluorescence (SF), the coherent light burst from synchronized quantum emitters, has been demonstrated in perovskite quantum dot superlattices. However, limited control over self-assembly, heterogeneity and emitter properties has hindered systematic exploration of cooperative...
