Eliezer Estrecho studies the behaviour of exciton-polaritons. At FLEET, as part of the Centre’s Research theme 2: Exciton superfluids, he worked with theme leader Prof Elena Ostrovskaya at the ANU, currently studying condensation of polaritons in gallium-arsenide-based microcavities using single-shot experiments and large optically induced traps. He is also working on creating polariton condensates using atomically-thin materials.
