Abstract:
Quantum cooperativity is evident in light-matter platforms where quantum-emitter ensembles are interfaced
with confined optical modes and are coupled via the ubiquitous electromagnetic quantum vacuum.
Cooperative effects can find applications, among other areas, in topological quantum optics, in quantum
metrology, or in quantum information. This tutorial provides a set of theoretical tools to tackle the behavior
responsible for the onset of cooperativity by extending open quantum system dynamics methods, such as
the master equation and quantum Langevin equations, to electron-photon interactions in strongly coupled
and correlated quantum-emitter ensembles. The methods are illustrated on a wide range of current research
topics such as the design of nanoscale coherent-light sources, highly reflective quantum metasurfaces, or
low intracavity power superradiant lasers.
