One of the success stories of quantum physics is how individual quantum particles have been controlled and manipulated for quite some time. However, the realisation of a fully controllable, strongly interacting and coherent quantum system, consisting of many particles, is an outstanding challenge. A new frontier of quantum physics has recently emerged utilising photons strongly coupled to quantum atomic gases, such as Bose-Einstein condensates and atoms trapped in optical lattice potentials. These cold atomic gases cooperatively coupled with light provide a rich strongly interacting quantum many-body system. Long-range interactions between atoms occur through exchange of photons. The atoms can also similarly be considered of mediating interactions between photons. The aim of the project is to study such long-range dipole-dipole interactions between the atoms and their cooperative behaviour.
The driving forces of quantum optics are quantum technologies that utilise quantum phenomena for higher precision measurements and for quantum information processing. In the systems with strongly coupled quantum atomic gases and light, the interactions can be engineered and manipulated for applications in quantum technologies and to simulate novel strongly interacting quantum systems with, e.g., non-trivial topologies.
