Our paper on ultrafast coherent polariton transport has just been published in Advanced Science, as part of the Rising Stars collection! Another great outcome for our fruitful collaboration with Akshay Rao at Cambridge. Not only are we able to distinguish bright polaritons from incoherent dark states, we also reveal for the first time how long-range polariton transport must involve population interchange with the reservoir. Even simple cavities turn out to be very complex systems, but therein lie the most exciting opportunities. Check it out here!
