Mitko Oldfield is an experimental physicist specialising in terahertz time-domain spectroscopy and exciton-polariton condensation, who at FLEET worked with A/Prof Agustin Schiffrin and Dr Gary Beane at Monash University within FLEET’s research themes 2 and 3. Mikto’s research focuses on forming a polariton condensate in high Q-factor microcavities through the use of a terahertz pumping beam generated via optical rectification. The aim is a polariton condensate that is coherent both spatially and temporally in the cryogenic regime, with the potential of translating this to room temperature through the use of perovskite-based microcavities.
