Superabsorption [1], the process by which an ensemble of atoms collectively enhances the rate at which it converts radiation energy into electronic excitation has been proposed in a variety of nanostructures such as arrays of quantum dots, molecular rings, and recently experimentally demonstrated with atomic [3] and molecular systems [4] where it was enabled by highly sophisticated control approaches. However, the exotic experimental conditions that were required present an impediment to harnessing the effect for practical applications.

In this project, we will study a promising different approach for realising superabsorption under much less demanding conditions. Specifically, we shall study a collection three level emitters inside a conventional microcavity. In this setup the necessary quantum control is provided by an external global microwave drive which allows the coherent suppression of emission pathways [2].

In the later stages of the project, we will develop blueprints for experimental exploration and implementation together with our network of experimental collaborators.
The realisation of superabsorbing devices will open up the prospect of a new class of quantum nanotechnology [4] with applications including photon detection and light-based power transmission.
