- First snapshot of exciton-polariton Bose-Einstein condensation (BEC) in an inorganic semiconductor
- Unique opportunity to understand details of BEC without statistical averaging
- Key to fundamental understanding of exciton-polaritons
An ANU advance provides never-before-achieved ‘snapshot’ of Bose-Einstein condensation.
Previously, observations of exciton-polaritons in a Bose-Einstein condensate were limited to statistical averaging over millions of condensation events.
‘Snapshot’ imaging of polaritons forming a condensate in a typical inorganic semiconductor was considered impossible.
Now, FLEET researchers at the Australian National University have led an international study imaging exciton-polaritons for the first time as a ‘single shot’, rather than averaging.
