- 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. The analytical approaches are developed
for ensembles of identical two-level quantum emitters and then extended to more
complex systems where frequency disorder or vibronic couplings are taken into
account. The relevance of the approach ranges from atoms in optical lattices to
quantum dots or molecular systems in solid-state environments.
