Quantum Polaritonics

An international research partnership of state-of-the-art experimental laboratories and theoretical groups between the University of Cambridge, MIT-Skoltech, and the University of Southampton.

Room Temperature Polaritonics

Circumventing the challenges of epitaxial growth, polariton condensates are also realised in soft-matter organic microcavities. In collaboration with IBM and the University of Sheffield we are investigating the potential of organic microcavities at ambient condition in sustaining polariton condensation and the application of organic polariton condensates for imprinting polariton lattices, a promising platform for quantum simulators, and as optical amplifiers.
